摘要
合成了一例基于二氰基异佛尔酮的近红外荧光染料,通过核磁共振氢谱以及高分辨质谱验证了其结构。研究了其在不同溶剂中的光谱性质,结果表明该染料最大发射波长达644 nm(DMSO溶剂中)并具有大的斯托克斯位移。
A near-infrared fluorescent dye based on dicyanoisophorone is synthesized with its structure elucidated by 1H NMR and HRMS.The spectroscopic properties acquired in different solvents are studied,and the results show that the dye exhibits an emission maximum of 644 nm(in DMSO)and a relatively large Stokes shift.
