摘　　要：Several planar conjugated polymers and model compounds containing pyrene units are synthesized.The pre-cursor polymers and model compounds are obtained through the Pd(0)-catalyzed Suzuki reaction,then the planar structure is formed through intramolecular cyclization in the presence of acid.We investigate the regioisomers in intramolecular cyclization reaction by using model compounds,suggesting that the syn-and anti-structures are formed in ladder-type polymer LP1,and the syn-structure is more easily formed in LP3.The planar conjugated polymers and model compounds show untypical features of ladder-type polymers,they display broad absorption and blue or blue-green emission in solution,and interchainπ-πstacking in film still occurs.Moreover,the new polymers and model compounds are characterized by nuclear magnetic resonance(NMR)spectroscopy,gel-permeation chromatography(GPC)and cyclic voltammetry(CV).
