摘要：New conjugated rigid-rod polymers, poly(p-phenylene-benzobisoxazole) (PBO) poly (benzobiso-xazole-2,6-diylvinylene) (PBOV) and poly (benzobisoxazole-2, 6-diyldivinylene) (PBODV) were synthesized, and their molecular structures, thermal stabilities and morphology of polymers were determined by FTIR, H-1-NMR, TGA and WAXD respectively. The photophysical properties of polymer/MSA solutions were investigated by UV and photoluminescence spectroseopies. The UV spectra and photoluminescence spectra of these new polymers in methanesulfonic acid suggest that the absorption spectra and optical bandgap of PBODV and PBOV have a red shift compared with those of the conjugated PBO. That is caused by the different conjugation structures in molecular chains of PBO, PBOV and PBODV.
