π-Conjugated polymeric phthalocyanine for the oxidative coupling of amines.

A cross-linked pi-conjugated polymeric cobalt phthalocyanine material was developed by a facile, economical, scalable, and solid-phase synthesis method. In addition to being highly recyclable, this material showed greatly enhanced activity for the aerobic oxidative coupling of amines compared with a molecular catalyst before heterogenization, indicating good prospects for the material with a pi-conjugated electronic character.
