The organic carbazole-cyanobenzene push-pull dye 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene was derivatized and attached to carbon or indium-doped tin oxide (ITO) electrodes by simple diazonium electrografting. The surface-bound dye is active and stable for the visible light photosynthetic isomerization of a wide range of functionalized stilbene and cinnamic acid derivatives. Up to 87,000 net turnovers were obtained for the isomerization of -stilbene. The isomerizations can be carried out in air with a 33% reduction in the rate. The ITO photoelectrodes are also active and stable toward photo-oxidations under basic and acidic conditions.
有机咔唑 - 氰基苯推拉染料1,2,3,5 - 四（咔唑 - 9 - 基） - 4,6 - 二氰基苯通过简单的重氮电接枝进行衍生化，并附着在碳或铟掺杂氧化锡（ITO）电极上。表面结合的染料对于多种功能化的芪和肉桂酸衍生物的可见光光合异构化具有活性且稳定。对于 - 芪的异构化，净周转数高达87000。异构化可以在空气中进行，速率降低33%。ITO光电极在碱性和酸性条件下对光氧化也具有活性且稳定。
