Synthesis and supramolecular organization of regioregular polythiophene block oligomers.
The Journal of organic chemistry, 2010Co-Authors: Sébastien Clément, Julien De Winter, Christophe M L Vande Velde, Jean-yves Balandier, Franck Meyer, Sergey Sergeyev, Olivier Coulembier, Pascal Gerbaux, Yves Geerts, Roberto Lazzaroni, Matthias Zeller, Philippe DuboisAbstract:The self-assembly of functional polythiophenes was studied by a bottom-up approach "from molecule to polymer". The synthesis and the X-ray structure of 2,5-dibromo-3-styryl and 3-2',3',4',5',6'-pentafluorostyryl-thiophenes revealed a supramolecular arrangement controlled by pi-pi interactions between the aromatic rings. A [2 + 2] Photocyclization reaction in the solid state of (E)-1-2',5'-dibromo-3'-thienyl-2-pentafluorophenylethene triggers the formation of a rare cycloadduct comprising thiophene rings. The X-ray analysis confirmed its rctt stereochemistry. The synthesis of P3HT-b-P3ST and P3HT-b-P3STF block oligomers was achieved by a GRIM method in good yields. An indirect proof of well-defined nanostructured organization was provided by the partial Photocyclization of pendant styryl moieties under UV irradiation.

n type organic semiconductor bisazacoronene diimides efficiently synthesized by a new type of Photocyclization involving a schiff base
RSC Advances, 2012Co-Authors: Youdi Zhang, Zhenbo Zhao, Xiaomei Huang, Jun Li, Xin Guan, Kaichen Zhang, Chuanhui Cheng, Yi XiaoAbstract:Novel bisazacoronene bisimides (bisaza CBIs) were efficiently synthesized via a new type of Photocyclization involving a Schiff base. One of the bisaza CBIs self-assembles into nanobelts and shows reasonable electron mobility in a space-charge-limited current device.
