A recrystallization process with enhanced nucleation by a dilute KOH aqueous solution is used to create nano from bulk metal phthalocyanines (MPcs). Cobalt phthalocyanine (CoPc) nanorods (similar to 20 nm in width and similar to 60 nm in length) and copper phthalocyanine (CuPc) nanorods (similar to 30 nm in width and several hundred nano meters in length) are prepared from bulk CoPc and CuPc, respectively. It indicates the strength of the interaction force between MPcs and H2O molecules possibly affects the size of the nano particles. The formation of nano MPcs and purification were accomplished simultaneously, providing a facial way to turn bulk MPcs into nano with high purity. (C) 2016 Elsevier Ltd. All rights reserved.
