摘要
合成了三个新的以2-(4-氨基-2-羟基苯基)苯并噻唑(4-AHBA)为核的聚芳醚树枝状化合物(1a^1c),其结构由1HNMR,13C NMR,IR,MS和元素分析表征。研究了1和4-AHBA在氯仿中的紫外吸收光谱和荧光发射光谱,结果表明,1与4-AHBA相比,紫外吸收强度大大提高,且最大吸收波长从349 nm红移至352 nm,荧光最大发射强度增强26倍~29倍。
Three novel poly （ aryl ether） dendrimers （ 1a - 1c） with 2-（4-arnino-2-hydroxyphenyl） benzothiazole（4-AHBA） core were synthesized. The structures were characterized by 1H NMR, 13C NMR, IR, MS and elemental analysis. The UV absorption and fluorescence emission spectra of 1 4-AHBA and were investigated in chloroform solution. In comparison with 4-AHBA, the UV absorption intensifies of 1 were significantly increased with a red-shift of the maxium absorption wavelength from 349 nm to 352 nm, and the fluorescence intensifies of 1 were enhanced up to 26 -29 folds.
