摘要：

Novel conjugated polymers 9a-c possessing the phosphole ring with the 5-member fused carbocycle were synthesized by palladium catalyzed coupling reaction of 1-phenyl-2,5-bis(p-bromophenyl)phosphole 7 with diethynylarenes 8a-c. The obtained polymers 9a-c had the regio-regulated 2,5-substituted phosphole ring in the polymer main chain, and were characterized by H-1, C-13, P-31 NMR, and FTIR. The P-31 NMR spectra revealed that the extension of pi-conjugation changed the phosphole ring angles. The optical properties of polymers 9a-c were independent of the size of the fused carbocycle.
