摘要：

The synthesis of poly(4,4'-dinonyl-2,2'-bisoxazole-5,5'-diyl) (PNBO) was performed through a nickel-mediated coupling of 5,5'-dibromo-4,4'-dinonyl-2,2'-bisoxazole. The solid-state morphology of PNBO was determined by powder X-ray diffraction (XRD) which showed strong peaks due to lamellar spacing and three-dimensional ordering. The polymer has absorbance maxima of 446 and 464 nm in solution, and 475 nm in the film. A low wavelength shoulder near 510 nm is ascribed to the absorption of aggregated molecules. The emission spectra are concentration dependent and consistent with emission from excimers. Essentially all the emission in the solid state is due to excimers. The physical and chemical properties of PNBO are compared to the sulfur analogues, poly(4,4'-dinonyl-2,2'-bithiazole-5,5'-diyl) (PNBTz) and poly(3-alkylthiophene)s.
