properties. The selective synthesis of unsymmetrical systems, particularly phthalocyanines, has remained a significant unmet challenge. Porphyrin‐phthalocyanine hybrids offer the potential to combine the favorable features of both parent structures, but again synthetic strategies are poorly developed. Here we demonstrate strategies that give straightforward, controlled access to differentially substituted
酞菁和卟啉通常是广泛应用中选择的支架。合成技术的进步使得可以定制衍生物,定制其特性。不对称体系(特别是酞菁)的选择性合成仍然是一个尚未解决的重大挑战。卟啉-酞菁杂化物提供了结合两种母体结构的有利特征的潜力,但合成策略仍然缺乏开发。在这里,我们展示了通过芳基氨基异吲哚 (A) 引发剂和互补邻苯二甲腈 (B) 之间的反应,直接、受控地获得差异取代的内消旋芳基四苯并三氮杂卟啉的策略。前体和反应条件的选择允许选择性制备 1:3 Ar-ABBB 和独特的 2:2 Ar-ABBA 功能化杂化物。
