摘　　要：In this paper,a novel monomer(5-(4-(4-vinylbenzyloxy)phenyl)-4,5-dihydro-1,3-diphenyl-1H-pyrazole)(StODO) with strong blue emission is synthesized,and its homopolymer(Homo-PStODO)is prepared by radical polymerization.The monomer and the homopolymer are characterized by 1H-NMR,Infrared Spectrum,HPLC,elemental analysis and GPC respectively.Then,we study the fluorescence emission spectra of StODO and its polymer,and investigate the influence on fluorescence emission spectra by solution concentration and solvent polarity.The results show that they all have high fluorescent quantum yield and strong fluorescent intensity.In this paper, a novel monomer （ 5- （ 4 - （ 4 -vinylbenzyloxy ） phenyl ） -4,5-dihydro-1,3 -diphenyl-1H-pyrazole ） （ StODO ） with strong blue emission is synthesized, and its homopolymer（Homo-PStODO） is prepared by radical polymerization. The monomer and the homopolymer are characterized by l H-NMR, Infrared Spectrum, HPLC, elemental analysis and GPC respectively. Then, we study the fluorescence emission spectra of StODO and its polymer, and investigate the influence on fluorescence emission spectra by solution concentration and Solvent polarity. The results show that they all have high fluorescent quantum yield and strong fluorescent intensity.
