Ultrasound has been found to enhance N-substitution against elimination in the reaction of carbazole-containing bromides 3 with a Disperse Orange 3 derivative 2 under PTC condition. Upon using combined PTC and ultrasound conditions, a series of bifunctional molecules 1 have been prepared to possess charge-transporting agents and nonlinear optical chromophores in 2:1 ratio.
已经发现,在PTC条件下,在含咔唑的溴化物3与分散橙3衍生物2的反应中,超声波增强了N-取代抵抗消除。在结合使用PTC和超声条件的情况下,已准备了一系列双功能分子1,使其具有电荷传输剂和非线性光学发色团,其比率为2:1。
