Synthesis of poly(p-phenylene-vinylene)derivative having amphiphilic substituents by palladium-catalyzed three-component coupling polymerization of p-bromophenylallene and nucleophile containing oligo-oxyethylene units

摘要

The palladium-catalyzed three-component coupling polymerization of p-bromophenylallene and a nucleophile possessing oligo-oxyethylene units was performed to give a poly(p-phenylene-vinylene)derivative having amphiphilic substituents on each vinylene unit in a high yield. The polymer was found to be soluble in organic solvents such as benzene,chloroform,N,N-dimethylformamide,and methanol,whose number-average molecular weight (M_n)and the molecular weight distribution (M_w/M_n)were estimated as 8,600 and 1.76,respectively.
