摘要

Salicylaldimine Zn(Ⅱ) complexes bearing azobenzene moieties were prepared to catalyze ring opening polymerization of various cyclic esters.The different reactivities of the trans and cis isomers of the zinc complexes provide a facile strategy to control polymerization processes as well as the compositions of the resultant polymers.
