Synthesis and Solid-State Polymerization of 4-(Dimethylamino)phenylbutadiyne Derivatives and Their Charge-Transfer Complexes

摘要

Five urethane derivatives of 8-[4-(dimethylamino)phenyl]octa-5,7-diyn-1-ol were syn thesized. They could be polymerized in the. solid state to give conjugated backbones although structural regularity seemed to be not so high. Formability of charge-transfer (CT) complex of one of the urethane derivatives and bis[4-(dimethylamino) phenyl]butadiyne as a reference compound with acceptors, such as 1,4-benzoquinone, 2,4,7-trinitmfluorenone etc., were investigated by solution mixing and powder co-grinding methods. In some cases, the CT complex formability was changed by the preparation method.
