A novel family of π-donor molecules, the diselenadiazafulvalenes (DSeDAFs), is presented. The synthetic approach to these donors, from o-nitroaniline, allows the formation of N,N′-dimethyldibenzoDSeDAF and N,N′-ethylenedibenzoDSeDAF. Comparative electrochemical study of these π-donor molecules demonstrates their excellent donor ability and the stabilizing effect of the ethylene bridge on the cation radical species.
本文介绍了一种新型的π供体分子家族--二硒二氮杂富戊烯(DSeDAF)。这些供体的合成方法来自邻硝基苯胺,可以形成 N,N′-二甲基二苯并二硒代二苯并呋喃和 N,N′-乙烯二苯并二硒代二苯并呋喃。对这些π-供体分子进行的比较电化学研究表明,它们具有出色的供体能力,而且乙烯桥对阳离子自由基具有稳定作用。
