| Abstract: | A series of random copolymers of poly(p-phenylenebenzobisoxazole)-copoly(9,9-dioctyl fluorenol benzobisoxazole)(PBO-co-PBOF) with different PBOF content were synthesized through condensation polymerization.X-ray diffraction,UV-Vis absorption and photoluminescence spectroscopy were used to study the effect of the structures on the modalities and optical properties of the copolymers.Compared with PBO,amorphous structures of the copolymers were observed with the existence of fluorene units in the main chains.T... |
