摘　　要：Comprehensive Summary Vinylene linked covalent organic frameworks(cOFs)have drawn extensive attention due to their desirable stability,carbon conjugation and opto-electronic properties.Suitable catalyst is a key factor in the synthesis of vinylene linked COFs,and proton acids and bases are widely reported as catalysts so far.Herein,we report the synthesis of vinylene linked cOFs using Lewis acid ZnCl2 as catalyst for the first time.Four COFs with hexagonal pores of different sizes are synthesized by the reaction of 2,4,6-trimethyl triazine and a series of aromaticaldehydes.
