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] carbazole}(P1) and poly{3-[4-(prop-2-ynyloxy)phenyl-N-butyl]carbazole}(P2), were prepared using [Rh(nbd)Cl]2-Et3N as catalyst. The polymers were soluble in common organic solvents such as CHCl3 and THF. 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.
