What was your inspiration in becoming a chemist?

I was immediately interested in Chemistry when I started to learn it at school. What I really enjoyed was to achieve some little experiments. So I asked my parents to buy me a Chemistry lab playset but they never did. I think that they were frightened about what my brother and I could do with it…

 What was the motivation to write your Polymer Chemistry article ?

In our team, we have been interested since a long time on phosphorus-based polymers. I am notably currently working on a book named “Phosphorus-based polymers: from synthesis to applications” as a co-editor which will be published soon by the RSC. We also have a great expertise on controlled radical polymerisation. As a consequence, we thought that combining both phosphorus and RAFT was a good idea to achieve polymers with well-controlled architecture, thus leading to interesting properties of the produced materials. In our article (DOI: 10.1039/C3PY00426K), we notably describe for the first time the controlled polymerisation of a phosphonated containing methacrylate, namely the dimethyl(methacryloyloxy)methyl phosphonate (MAPC1), by the RAFT process. This work is of great interest as successful “living” radical homopolymerisation of MAPC1 and related monomers was never reported in the literature. Additionally, we recently reported the RAFT polymerisation of phosphonated-based acrylamide in another paper also published in Polymer Chemistry (Polymer Chemistry, 2013, 4, 795).

Why did you choose Polymer Chemistry to publish your work?

I consider Polymer Chemistry as a leading journal in the field of polymers, with a broad audience. Impact factor is excellent, reviewers’ comments are very constructive and publication is very fast.

In which upcoming conferences may our readers meet you?

I will be attending the 34th Australasian Polymer Symposium at the beginning of July (7th – 10th July 2013) which will be held at Darwin, in the Northern Territory of Australia. I will notably speak about RAFT polymerisation of phosphonated-based monomers.

How do you spend your spare time?

I spend my spare time with my two daughters and my husband. We enjoy being all together, at the moment gardening, especially growing some tomatoes and strawberries in our vegetable garden.

Which profession would you choose if you were not a scientist?

I think I never thought to do something else, really. But I would have enjoyed being a pianist, even if I never learned to play… but it is not too late to do it!

Paper of the week: One-pot, additive-free preparation of functionalized polyurethanes via amine–thiol–ene conjugation

Facile synthetic and modification procedures of functionalized polymers have been the subject of extensive fundamental and applied research efforts during the last decade. The concept of ‘click’ chemistry induced a transition towards ‘on-demand’ preparation of tailored polymeric systems. The toolbox of research labs is currently loaded with a variety of established ‘click’ reactions, offering ample possibilities for macromolecular design and synthesis. Moreover, the development and valorization of novel polymer materials with a broad range of applications (medicines, electronics, bioconjugation, labeling, etc.) significantly promoted interdisciplinary research. The elaboration of innovative procedures and the combination of existing reactions in multi-step one-pot sequences further exemplify the scientific eagerness to study the possibilities and limitations of ‘click’ chemistry to the full extent.

Filip Du Prez et al. have elaborated a straightforward, isocyanate-free method for the synthesis of functionalized polyurethanes, based on amine–thiol–ene conjugation. Aminolysis of a readily available AB′-urethane monomer, containing both an acrylate (A) and a thiolactone unit (B′), facilitates the preparation of various reactive thiol–acrylates. In situ polymerization via Michael addition proceeds under ambient conditions, yielding polyurethanes with a large variety of chemical functionalities. Side-chain functionality originates from the modular use of different amines, allowing for the introduction of pendent functional groups (e.g. double bond, triple bond, furfuryl, tertiary amine, morpholine) along the polyurethane backbone. Extensive model studies revealed the kinetic profile of this reaction sequence and excluded the occurrence of competing reactions, such as aza-Michael addition and disulfide formation. This mild one-pot reaction requires no additives or external trigger and the obtained polyurethanes remain soluble throughout the process, enabling post-polymerization modification in the same reaction medium.

One-pot, additive-free preparation of functionalized polyurethanes viaamine–thiol–ene conjugation by Pieter Espeel, Fabienne Goethals. Frank Driessen, Le-Thu T. Nguyen and Filip Du Prez, Polym. Chem. 2013, 4, 2449-2456.

Author of the Week: Prof. Chang-Ming Dong

 

Prof. Chang-Ming Dong was born in Henan province of P. R. China in 1972. He received his Ph.D. degree in Polymer Chemistry & Physics under the supervision of prof. Xin-De Feng and prof. Kun-Yuan Qiu from Peking University in 2001. After about two-year postdoctoral research with prof. Elliot L. Chaikof in school of medicine of Emory University (now working at Harvard University), he joined the faculty of Department of Polymer Science & Engineering in Shanghai Jiao Tong University (SJTU, Shanghai, P. R. China) in January, 2004. He was promoted to full professor in January, 2009, and currently focuses on the design and synthesis of biodegradable and biomimetic polymeric biomaterials (such as PLA, PCL, PLGA, polypeptide, and glycopolymer) and their applications in drug delivery and nanomedicine. He published near 60 peer-reviewed papers with a total citation of over 800 and an H-index of 22. He received the support of “Project of New Century Talents” from the Education of Ministry of China and the SMC young faculty award from SJTU.

What was your inspiration in becoming a chemist?

The curiosity for exploring new natural phenomena, solving the basic problems that the human being faces, and also including the dream to become a scientist drive me to work hard for natural sciences including chemistry, especially polymer chemistry.

What was the motivation to write your Polymer Chemistry article? (DOI: 10.1039/C3PY21121E)

Since 2004, I focused on the design and synthesis of biodegradable and biomimetic polymeric biomaterials and their applications in stimuli-sensitive drug delivery and nanomedicine. Especially, we recently paid more attention to the near infrared (NIR) light-responsive biodegradable polymers and the related nanomedicines, which hold great potentials in on-demand (in a continuous or pulsatile mode) and spatiotemporal (when and where) drug delivery and clinical medicine. These results drive me to write a review paper in Polymer Chemistry.

Why did you choose Polymer Chemistry to publish your work?

RSC is one of the leading societies for chemistry in the world. Polymer Chemistry is an emerging high-quality journal in Polymer Science and has a wide readership in the world. In addition, it has a quick submission and review system. So I am pleasant to report our future fundamental works in this journal.

In which upcoming conferences may our readers meet you?

I like to participate in some major and specialized meetings, e.g., the polymer science meeting of China or some meetings on the controlled drug release.

How do you spend your spare times?

Besides teaching and doing research in SJTU, I am willing to spend more time with my family (especially my little lovely daughter). Watching International or National News from TV and running every week are also my hobbies.

Which profession would you choose if you were not a scientist?

I would become a teacher in middle school or a farmer in my hometown if I were not a polymer chemist.

Paper of the week: Furan and benzochalcogenodiazole based multichromic polymers via a donor–acceptor approach

Conjugated aromatic polymers have attracted great attention since 1970s. Myriad of studies have been reported on five-membered heterocycles containing polymers such as polypyrroles, polythiophenes and their derivatives due to their susceptible electronic and optical properties. Recent studies showed that furan containing polymers have some priorities over thiophene based ones for the application of polymer organics in advanced technological applications. For instance, the greater electron withdrawing ability of furan is capable of reducing the HOMO energy level of the D parts in the solar cells, which results in the high open circuit voltage.

Cihaner, Onal and their coworkers have designed and synthesized two new furan and benzochalcogenodiazole based monomers, namely 4,7-di(furan-2-yl)benzo[c][1,2,5]-selenadiazole (FSeF) and 4,7-di(furan-2-yl)benzo[c][1,2,5]thiadiazole (FSF), via a donor–acceptor–donor approach. The monomers were electrochemically polymerized via potentiodynamic or potentiostatic methods. The monomers and their polymers exhibited lower oxidation potentials (1.16 V and 1.06 V for monomers; 0.93 V and 0.80 V for polymers vs. Ag/AgCl) and red shifts of the whole dual-band absorption spectra upon moving from S to Se. Intramolecular charge transfer properties of the monomers and the polymers were demonstrated by using electroanalytical and optical methods. Also, the polymers PFSeF and PFSF were multicolored at different redox states and have low band gaps of 1.43 eV and 1.61 eV, respectively.

Furan and benzochalcogenodiazole based multichromic polymers via a donor–acceptor approach by Merve İçli-Özkut, Halil İpek, Baris Karabay, Atilla Cihaner and Ahmet M. Önal Polym. Chem., 2013, 4, 2457-2463

Paper of the week: Facile synthesis of chain-end multifunctional polymers

Chain-end functionalization of synthetic polymers is an established route to functional soft materials and the resulting end-functionalized polymers are useful in many applications. However, current synthetic approaches that do not involve functional group transformations and protection/deprotection protocols are limited to installation of a single type of functionality at the polymer chain-end. This needs to be addressed as chemically heterogeneous multifunctionalization is expected to increase the range of possible applications as well as performance of the functionalized materials

Graphical abstract: Protecting-group-free synthesis of chain-end multifunctional polymers by combining ATRP with thiol–epoxy ‘click’ chemistry

In this context, by combining atom-transfer radical polymerization (ATRP) with thiol–epoxy‘click’ chemistry, Khan and co-workers described a general and effient synthetic scheme, free from the usual protection/deprotection requirement of organic synthesis, for installation of two different types of functional groups at a polymer chainend. This strategy also allowed for total control over the number of the chain-end functionalities. In essence, the present strategy established a novel, modular and efficient route to chain-end multifunctional polymers with chemically complex yet molecularly precise structures and is expected to impact the current design of functional soft materials targeted for sophisticated applications.

Protecting-group-free synthesis of chain-end multifunctional polymers by combining ATRP with thiol–epoxy ‘click’ chemistry by Ikhlas Gadwal and Anzar Khan, Polym. Chem., 2013, 4, 2440-2444.
