Two novel water‐soluble indocyanine dyes were synthesized. Their chemical structures were confirmed by 1H NMR, IR, MS and UV‐vis techniques. The absorptions of the prepared dyes in different solvents were measured. Two dyes exhibited negative solvatochromism, with a blue shift of the absorption and an emission maximum in (bovine serum albumin) protonic solvent relative to non protonic solvent. The
合成了两种新型的水溶性吲哚菁染料。通过1 H NMR,IR,MS和UV-vis技术证实了其化学结构。测量了所制备的染料在不同溶剂中的吸收率。两种染料显示出负溶剂溶剂变色,相对于非质子溶剂,在(牛血清白蛋白)质子溶剂中吸收发生蓝移,并且发射最大值。研究了游离态和BSA两种情况下染料的荧光特性。在BSA的存在下,Dye2的荧光强度显着增强。染料2可以作为荧光染料用于水溶液中BSA的检测。
