The Chemical Science Symposium 2020 – An experiment in virtual conferencing and embracing digital platforms

26 Oct 2020

By Jeremy Allen.

At the end of September we held our annual symposium – the second in a new series of symposia that intend on bringing together researchers from a broad cross-section of the chemical sciences community. The theme and subtitle for this symposium was How can machine learning and autonomy accelerate chemistry? This symposia series, the first of which was held at our historic headquarters in Burlington House, London, has an ambition to enhance social networking between members of our research community while showcasing recent developments by a diverse set of international speakers. They also present an opportunity for our delegates to interact with our journal staff, Editorial Board members and learn more about how we are improving the peer review experience at Chemical Science – for example through our new submission system and article tracker.

Earlier this year, as the COVID pandemic began disrupting our way of life and pushing the community to adapt their dissemination routes and means to network, we took the decision to move our symposium to an online environment – a new experiment for both Chemical Science and the wider Royal Society of Chemistry. The programme was adapted to encourage engagement in this virtual setting while continuing to deliver some exceptional science from our invited speakers and contributing poster presenters. Overall, the result of this was a resounding success!

The presentations from our academia and industry-based speakers were very well received – with the following topics covered:

Yousung Jung KAIST, South Korea: Efficient exploration of solid state chemical space using machine learning
Graeme Day University of Southampton, UK: Building a computational engine to guide the autonomous discovery of molecular materials
Joshua Schrier Fordham University, UK: Autonomous materials discovery: promise, pitfalls, and progress
Jill Becker Kebotix, USA: Accelerating materials innovation: discovery of electrochromic materials for smart windows
Jacqueline Cole University of Cambridge, UK: Accelerating materials discovery with data mining and machine learning
Lee Cronin University of Glasgow, UK: The Chemical Oracle
Kerstin Thurow University of Rostock, Germany: Suitable automation systems for accelerating chemical research
María José Nieves Remacha Eli Lilly & Company, Spain: Autonomous chemical synthesis in flow for drug discovery

From left to right: Y. Jung, G. Day, J. Schrier, J. Becker, J. Cole, L. Cronin, K. Thurow, M. J. Nieves Remacha

In addition to these talks we also held a number of networking and discussion sessions, including one that focussed on the digital tools used by researchers both within and external to the chemical sciences and where the future of this discipline is heading. The discussion session, hosted by Chemical Science Editor-in-Chief Andrew Cooper and Associate Editor Alán Aspuru-Guzik complimented the work carried out by the Royal Society of Chemistry to publish a report on Digital Futures. We’ll report on this session separately.

As with all experiments, we are now in a position to reflect – some things were very successful, such as the quality of our presenters, the science being discussed and the level of engagement during our scientific sessions. However there were also challenges and aspects that need further thought in the future. Outside of software limitations and the obligatory technical hitches during a conference about digital research, perhaps predictably, networking was clearly not nearly as simple as you would find during a physical meeting. While we had a range of fantastic posters at the meeting and designated networking sessions, neither the virtual poster hall nor the chat rooms replicated the same random and chance encounters and discussions that we’re all used to and make a physical meeting such a useful and interesting place to be. So while we looked to give opportunities for delegates to connect, this is clearly an area we need to rethink. As the pandemic continues, the future effects this will inevitably have on the conferences landscape are unknown – now is a time for both researchers and event organisers to look to enable new ways to facilitate this. How do we continue the kinds of discussions that lead to knowledge sharing, future collaborations and job openings in an organic way that doesn’t require delegates to be forced into a chat room and told to network? While we ponder this problem from our side, we’d be grateful for thoughts and ideas from our community too.

So what does all this mean for 2021 – plans are currently underway for the next iteration of this symposium series and we will announce further details as soon as we can! In the meantime we would also welcome your feedback – regardless of whether you attended this meeting, our first symposium or you are thinking about maybe attending in the future. What would you like to see at our future symposia and how do you think they should be held – a physical meeting, virtually or a mixture of the two?

We’d like to take this opportunity to thank all those involved with the symposium – from our Chairs and presenters through to our delegates – thanks for helping make this such a successful meeting in these challenging times. If you would like to share any thoughts on our symposium series or suggestions for future changes (or topics) please do get in touch with our team at chemicalscience-rsc@rsc.org

A radical twist to halogenations using boron tribromide

30 Sep 2020

By Samantha Apps, Web Writer.

Organoboranes are extremely useful reagents for chemical synthesis; their Lewis acidic nature makes them reactive towards nucleophilic species, and their ability to participate in free-radical processes widely expands their synthetic use. Trialkylboranes (BR₃) are the most widely studied in terms of borane radical chemistry, whereby alkyl radicals (R^●) can be generated through homolytic substitution at the boron atom under oxygen conditions to then participate in various alkylation reactions, as shown in Scheme 1a. This extremely mild radical-initiation system, using just O₂ instead of heat or light for radical generation, is highly desirable in chemical synthesis, particularly for the formation of thermally unstable products.

Scheme showing radical generation from organoboranes

Scheme 1: (A) Previously known radical chemistry with organoboranes and (B) radical reactivity using trihaloboranes.

Researchers in both China and the US have now applied this concept of radical generation using trihaloboranes for halogenation. Halogenation reactions are extremely important in chemical synthesis, since the resulting halogenated products are ideal precursors for installing a wide range of functional groups through substitution chemistry. Typically, halogenation of organic molecules using trihaloboranes has been attributed to their Lewis acidic nature, but the researchers have now shown that these reagents can also act as halogen radical donors (as shown in Scheme 1b).

The researchers selected boron tribromide (BBr₃) as a bromide radical donor (Br^●), since the B-O bond that forms upon radical generation using O₂ is much stronger than the B-Br bond that breaks, making the process thermodynamically favourable. They applied this approach to investigate the hydrobromination of cyclopropanes, for the novel and selective formation of the anti-Markovnikov haloalkane product. The researchers initially optimised the reaction of cyclopropylbenzene (1a) with BBr₃/O₂ and found that the addition of a proton source (e.g. H₂O or alcohol) was sufficient to terminate the radical reaction and give the anti-Markovnikov product (2a) as the major species (Scheme 2). Using these conditions, the substrate scope could be expanded for the hydrobromination of a wide range of cyclopropanes, including typically challenging alcohol or amine-functionalised substrates.

Reaction optimisation scheme and table for hydrobromination of cyclopropane with BBr3

Scheme 2: Initial reaction optimisation of hydrobromination of cyclopropylbenzene (1a) to give the anti-Markovnikov product (2a) as the major species.

To establish that the hydrobromination reactivity was occurring via a radical process rather than a possible acid-mediated pathway, the researchers conducted a series of control experiments. The addition of radical scavengers resulted in only the formation of the Markovnikov product, suggesting the radical process is necessary for the anti-Markovnikov selectivity observed. The absence of oxygen also shut down the reactivity, which further indicates the radical pathway as shown in Scheme 1b. Additional computations modelled a possible pathway analogous to the established radical alkylation using trialkylboranes, showing an energetically favourable radical pathway for the hydrobromination of cyclopropylbenzene using BBr₃/O₂(Figure 1).

Figure 1: The calculated energy profile for the hydrobromination reaction

The results in this study demonstrate that trihaloboranes, like trialkylboranes, can act as radical donors for halogenation reactions, allowing for previously unreported anti-Markovnikov selectivity in the hydrobromination of cyclopropanes. This radical reactivity could be applied in the future for the halogenation of many different organic molecules, giving way to new methods to affect selectivity that cannot be achieved using traditional acid-mediated pathways.

Aggregation makes fluorescent probes better and brighter

03 Sep 2020

By Samantha Apps, Web Writer.

Fluorescence, the phenomenon where a molecule re-emits light upon absorption of electromagnetic radiation, is used in biological imaging to visualise structures, processes and diseases. Emission of these fluorescent molecules, known as fluorophores, in the near-infrared region is particularly advantageous, allowing for enhanced tissue penetration and reduced photodamage. Near-infrared (NIR) fluorophores are therefore attractive probes for bioimaging but are currently limited with problems such as low brightness or quenching of the emission by aggregation.

To overcome this aggregation-caused quenching effect, researchers in China turned to fluorophores that have aggregation-induced emission (AIE) properties. Aggregation-induced emission (AIE) is a concept where molecules only fluoresce upon aggregation in concentrated solutions, and not in dilute solutions where they can freely rotate. The researchers therefore designed their fluorophore to contain the molecular rotor tetraphenylethene, that can induce AIE effects and therefore boost and brighten the fluorescence.

The researchers prepared a suite of fluorophores using a central donor-acceptor-donor core, with methoxy-tetraphenylethene (MTPE) as the donor and thieno[3,4,-b]pyrazine (TP) as the acceptor. Substituents on the TP acceptor were varied, and the effects on aggregation and the fluorescence were investigated. Density functional theory calculations gave the researchers insight into the molecular conformations of the fluorophores, as shown in Figure 1. The 3 variants all showed twisted geometries (top row, Figure 1), indicating high degrees of rotation, which could then be restricted through aggregation and give rise to the desired AIE effects. Additionally, the calculations measured electronic distributions, confirming high degrees of electron conjugation in the molecules (see the HOMO diagrams, Figure 1) that are essential for fluorescence.

Figure 1: Results from density functional theory calculations to show molecular geometries and electron conjugation within the suite of fluorophores

The fluorescence characteristics of the variants were measured by absorption and emission/photoluminescence spectra. The absorption spectra in DMSO (Figure 2a) shows absorptions between 518 and 543 nm, with the most red-shifted (longer wavelength) absorption displayed for the most conjugated variant (MTPE-TP3). The effect of aggregation on the fluorescence was measured by adding water (in which the fluorophores showed poor solubility) to the DMSO solutions, and the resulting photoluminescence intensities showed an increase with higher water fractions. This increase in brightness (i.e. intensity) is explained by the water affecting aggregation of the fluorophores and inducing the AIE effect (Figures 2b and c).

Fluorescence spectra and aggregation effects of AIE fluorophores

Figure 2: a) Absorption spectra of the fluorophore variants; b) photoluminescence spectra of the most conjugated variant, MTPE-TP3 with different water fractions; c) corresponding photoluminescence intensity plotted against water fractions for all three variants. d) to f) additionally indicate the effect of increased viscosity (and aggregation) upon glycerol addition to the fluorophores.

The researchers also formulated nanoparticles for each fluorophore variant to allow for better water solubility and therefore biocompatibility. They found that the absorption and emission of the nanoparticles became both brighter and more red-shifted and were now within the near-infrared range for favourable biological imaging. In vitro and in vivo testing of these nanoparticles in breast cancer cells and tumour-bearing mice verified that the AIE-nanoparticles are suitable for biological imaging, and indicate their potential to assist with tumour diagnosis in future clinical settings.
