Preparation and properties of two new soluble carbazole-containing functional polyacetylenes

Two new functional polyacetylenes bearing carbazole group as pendant,poly {3-（4-ethynylstyryl）-N-butyl]carba/ole}（P1） and poly{3-4-（prop-2-ynyloxy）phenyl-N-butyl]carbazole}（P2）,were prepared usingRh（nbd）Cl)₂-Et₃N as catalyst.The polymers were soluble in common organic solvents such as CHCl₃ and THK Their structures and properties were characterized and evaluated with FTIR,¹H NMR,UV,TGA,GPC,and CV,respectively.The results show that the polymers possess high thermal stability and well hole-injection property.
