Nucleophilic substitution reactions of 5,10,15-tris(pentafluorophenyl)corrole (1) with amines were examined as a post-modification route to functional corroles. Reaction of 1 with an excess of amine nucleophiles led to exclusive formation of 5,10,15-tris(4-amino-2,3,5,6-tetrafluorophenyl)-substituted corroles. In this nucleophilic reaction, 5- and 15-pentafluorophenyl substituents were found to be
5,10,15-tris(pentafluorophenyl) corrole (1) 与胺的亲核取代反应被检查为功能 corroles 的后修饰途径。1 与过量的胺亲核试剂的反应导致 5,10,15-三(4-氨基-2,3,5,6-四氟苯基)-取代的corroles 的独家形成。在该亲核反应中,发现 5- 和 15- 五氟苯基取代基比 10-位的取代基更具反应性。该取代反应用于制备ABC型corroles和corrole基有机凝胶。由于 H 型聚集体的形成,后者在非极性烃溶剂中表现出蓝移的 Soret 带和小的荧光量子产率。
