We invite you to visit the May issue of NJC.
An article by Kazuyuki Kuroda and co-workers (Waseda University, Tokyo, Japan) features on this month’s front cover. In this publication, the authors report the synthesis of a novel air-stable spherosilicate oligomer that can be trimethylsilylated leading to further chemical modification or condensed upon thermal-treatment to afford molecularly ordered hybrids. This silicate oligomer is an attractive building block for the preparation of silica-based nanomaterials such as metallosilicates or mesostructured materials.
“A spherosilicate oligomer with eight stable silanol groups as a building block of hybrid materials”, Kazufumi Kawahara, Hiroki Tachibana, Yoshiaki Hagiwara and Kazuyuki Kuroda New J. Chem., 2012, 36, 1210-1217. DOI: 10.1039/C2NJ20953E (Paper).
The inside cover was produced by Monika Stolar and Thomas Baumgartner (University of Calgary, Canada), presenting a series of donor/acceptor functionalized π-conjugated materials, in which the donor component is a 3(6)-carbazole unit and the acceptor component a 2(6)-dithienophosphole species. The new chromophores display a desirable and reversible stimulus-responsive behaviour with a significant red shift of the absorption and emission wavelengths in the presence of acids.
