Hot wheels: strapped porphyrin-based rotaxanes

28 Nov 2012

Mechanically interlocked architectures such as rotaxanes and catenanes are prime candidates for the construction of molecular machines and the fabrication of molecular electronic devices.

In this NJC paper, Kathleen Mullen and co-workers (Queensland University of Technology, Brisbane, Australia) report a “click” methodology towards bipyridinium porphyrin [2]rotaxanes. An X-ray study of the strapped zinc metalloporphyrin revealed that the wheel adopts a 1-dimensional coordination polymer arrangement in the solid state, in which an oxygen atom in the strap of one macrocycle is coordinated to the zinc metal center in an adjacent porphyrin ring.

Future work will investigate the photo- and electro-chemical properties of these interlocked architectures.

Water-soluble chromophores shining like a star

31 Aug 2012

In this NJC article, Cyrille Monnereau and his colleagues (University of Lyon, France) report an Atom Transfer Radical Polymerisation (ATRP) approach towards star-shaped chromophores, which bear hydrophilic oligomeric arms that form an “insulating shell” around the nano-sized molecules, resulting in their solubility in water with good conservation of their fluorescence quantum yield. These new amphiphilic chromophores are promising candidates for cellular fluorescence and photodynamic therapy. The authors claim that this synthetic strategy for photoactive species is straightforward and adaptable.

“Water-soluble chromophores with star-shaped oligomeric arms: synthesis, spectroscopic studies and first results in bio-imaging and cell death induction” Cyrille Monnereau, Sophie Marotte, Pierre-Henri Lanoë, Olivier Maury, Patrice Baldeck, David Kreher, Arnaud Favier, Marie-Therese Charreyre, Jacqueline Marvel, Yann Leverrier and Chantal Andraud, New J.

Hot paper : Eu(diketonato) Complexes with potential applications in biological assays.

31 Aug 2012

In this NJC paper, Marina Lezhnina et al (Muenster University of Applied Sciences-Chemical Engineering, Germany) report the synthesis and photophysical properties of Eu complexes attached to epoxy-functionalized phenantroline ligands.

The authors show how these complexes can be conveniently attached to thiol groups, in the present example gluthathione, and still retain the characteristic red emission of Eu centers.

How good are the crystallisation methods for co-crystals?

23 Jul 2012

In this NJC Hot paper, Fucke et al. attempt to answer a very important question relating to co-crystal formation and screening. Piroxicam, a non-steroidal anti-inflammatory drug, was chosen as a model system and subjected to extensive co-crystal screening using twenty different acids as co-crystal formers, six crystallisation techniques and five solvents. The work explores in comprehensive detail the use of different techniques for obtaining co-crystals and compares their efficacy. The authors offer several thoughts on how their results might usefully be applied to improve co-crystal screens.

Using imidazolium silanthiolates to simulate the interactions in the active site of cysteine proteases

18 Jun 2012

In this NJC paper, Anna Dolega and co-workers (Gdansk University of Technology, Poland) have prepared three imidazolium silanethiolates relevant to the active site of cysteine protease.

By using solid state characterization techniques and modeling, the authors were able to present the first example of proton transfer along the chain of NH^+…S^– hydrogen bonds. A cooperative effect in the chain consisting of silanethiolate and imidazole residues linked by NH^+…S^– hydrogen bond was proposed to be due to the polarization of electron density connected with the increase in the Mulliken partial charge on the sulfur atom.

“Naked-eye” detection of chirality

07 Jun 2012

Chiral analysis continues to receive considerable attention since enantiomers often differ in their pharmacological activity and pharmacokinetic profile.

In this NJC letter, Haibing Li and co-workers from Central China Normal University at Wuhan (P.R. China) report a colorimetric sensor that displays a selective and strong response to L-histidine resulting from the agglomeration of silver nanoparticles. The authors believe that the self-assembly of nanoparticles into clusters is an effective approach to improve the sensitivity of chiral detection.
