Abstract：A series of styrene derivatives with stilbene-like pendant were synthesized through heterogeneous Wittig reaction of triphenyl-(4-vinyl)-benzylphosphornium chloride with aromatic aldehydes. The substituted styrenic monomer, 4-(2-aryl)-vinyl-styrene, was strongly photoluminescent in solution and in solid state. Introduced electron-pushing substituents and lengthened conjugation both enhanced the emission intensity and led to a red shift of emission bands, with the maximum emission wavelength shifted from 378 to 494 nm. The fluorescece quantum efficiencies were determined by employing quinine sulfate as reference; and 4-(2-anthryl)-vinyl-styrene (AVS) possessed the highest quantum efficiency(λ=494 nm, Фf=0.635).
