ChemPlusChem 5/2013: Like Oil and Water
In the cover article, Martin Pumera et al. use self-propelled biocompatible capsules loaded with various surfactants and compared their influence upon movement of oil droplets. Their findings are expected to have great impact on potential applications of such capsules for environmental clean-up. Also, a report on visualizing hyperconjugation through UV-photoelectron spectroscopy is outlined by Vladimir Ya. Lee et al. Meanwhile, Pierre Frère et al. describe the synthesis as well as the optical, theoretical, electrochemical, X-ray, and electrical characteristics of new thiophene/furan-capped co-oligomers for organic field-effect transistors.

- Facile Synthesis of Phosphate-Functionalized MWCNT–TiO2 Nanocomposites as Efficient Photocatalysts and Insights into the Roles of Nanostructured Carbon

Pollutant breakdown: As depicted, the photogenerated electrons of TiO2 transfer to the multiwalled carbon nanotube (MWCNT) and are captured by adsorbed O2. Phosphate functionalization of MWCNTs promotes O2 adsorption to improve photogenerated charge separation of the resulting MWCNT–TiO2 composite.
- Is There BN Bond-Length Alternation in 1,2:3,4:5,6-Tris(biphenylylene)borazines?

All things being equal: The electrophilic aromatic bromination of 1,2:3,4:5,6-tris(biphenylylene)borazine yields the tribromo derivative that has only small bond-length alternation (BLA) according to X-ray crystallography and state-of-the art computations (see scheme). A re-investigation of the structure of the parent 1,2:3,4:5,6-tris(biphenylylene)borazine compound by experiment and theory reveals positional disorder of the borazine core.

No two ways about it: Two photo- and thermoisomeric compounds of [(H3ATSA)]⋅2 H2O and [Cd2(H2ATSA)4]⋅13 H2O have been prepared and their optical properties investigated as well as simulated by DFT and TDDFT calculations (see figure). The multiple chromic properties of these compounds may be exploited to create new photoactive devices.

Luminescent cap: The properties of a fluorescent conjugated polyelectrolyte and mesoporous silica nanoparticles have been combined to prepare a pH-controlled drug delivery and cellular imaging system by using a simple and general method (see scheme). The fluorescent conjugated polyelectrolyte was used as both the capping agent and the imaging probe with low cytotoxicity. It is a promising candidate for simultaneous diagnostics and therapeutics.

Tubulin as the target: The introduction of a hydrophobic group at position 7 of 9-fluorenone-2-carboxylic acid (see structure) generates new tubulin binders, the design of which is suggested by modeling studies. The antiproliferative activity on two different cell lines, fluorescent microscopy, flow cytometry, and sedimentation assay tests confirmed the supposed mechanism.
