Uniform octahedral zinc tetraphenylporphyrin (ZnTPP) microcrystals were obtained in a large scale by a facile, fast and surfactant-free process at room temperature. The effects of synthetic parameters such as solvent and concentration on the formation and morphology of ZnTPP were investigated. Furthermore, by varying the reaction time, both the morphology and the size of the ZnTPP microcrystals can be controlled.
