Abstract

The synthesis of hyperbranched oxadiazole-containg polyfluores using 'A₂ + A₂^′ + B₃' approach based on Suzuki polycondensation was investigated. The molecular structures of the sample polymer were characterized with high-resolution NMR spectroscopy and elemental analysis. The solubility was found to be poor in organic solvents for hyperbranched polymers with higher contents of 2-(4-bromophenyl)-5-(3,5-dibromophenyl)-1,3,4-oxadiazole monomer. The sample polyfluores showed stable blue light emission even after being annealed in the elevated temperatures in the N₂ and air.
