【摘要】 以邻氨基硫酚、炔丙胺、对氨基水杨酸为原料合成了一种末端带有炔基的2-(2’-羟基苯基)苯并噻唑类激发态分子内质子转移化合物,其与末端含有叠氮基的香豆素经Click反应生成目标化合物,化合物结构经~1HNMR、MS和元素分析表征.探讨了该化合物在溶液中的光物理性质及能量传递过程,表明分子内给体和受体间能量传递通过F?ster机制进行。更多还原

【Abstract】 A kind of 2-(2’-hydroxyphenyl)benzothiazole derivative containing alkynyl was synthesized via 2-aminothiophenol, 2-Propynylamine, 4-amino salicylic acid in this paper. The target compound was obtained by alkyne–azide "Click" cycloaddition between 2-(2’-hydroxyphenyl)benzothiazole and coumarin derivatives. The structure of the compound was characterized by ~1 H NMR, MS and elemental analysis. Luminescence mechanism of the target compound was discussed in solvent system. The energy transfer between donor and acceptor via F?ster mechanism was revealed.更多还原
