| 摘 要： | 吡唑啉衍生物在生物医药[1,2]应用的领域非常广泛.吡唑啉还是一种优质的发光材料[3],其发射波长位于450nm左右,具有很高的荧光量子效率,且发光波长窄,色纯度好,是一种纯正的蓝光.当吡唑啉环3位引入给电子基时,化合物则具有很高的荧光量子产率,可制得具有高热稳定性的空穴传输蓝光发光材料[4-6]和荧光探针[7].它还可以将吸收的不可见的紫外光转变为蓝色的可见光反射出来,从而增加了光线的反射率,使被其处理过的物体白度和光泽提高,所以吡唑啉又被做为荧光增白剂和荧光染料[8,9]进行广泛地应用.

| Abstract: | 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 solven... |
