许多注意被奉献给荧光灯特别在万用的应用与潜力染那些。反应在下面“点按”在 nonfluorescent 之间的条件 3 - azidocoumarins 和终端炔属羟生产了 3 -(1, 2, 3-triazol- 1 - yl ) cournarins,一种新奇类型荧光灯有强烈荧光的染料。新香豆素的结构被 1H NMR, MS,和红外系列描绘。荧光系列测量证明自从叠氮化物和炔属羟对生物系统相当惰性, triazolylcoumarins 和这按反应的优秀荧光性能是 bioconjugation 和 bioimaging 应用程序的一个有希望的候选人。
Much attention is devoted to fluorescent dyes especially those with poten tial in versatile applications.Reactions under "click" conditions between nonfluorescent 3-azidocoumarins and terminal alkynes produced 3-(1,2,3-triazol-1-yl)coumarins,a novel type of fluorescent dyes with intense fluorescence.The structures of the new coumarins were characterized by 1H NMR,MS,and IR spectra.Fluorescence spectra measurement demonstrated excellent fluorescence performance of the triazolylcoumarins and this click reaction is a promising candidate for bioconjugation and bioimaging applications since both azide and alkynes are quite inert to biological systems.
