can be easily tuned by chemical manipulation of the substituents on that privileged scaffold. Replacement of a OMe group at position 6 in 2-(hydroxyl)ethyl-naphthalimide derivatives by diverse amines, including 2-(hydroxyl)ethylamine, trans-(4-acetamido)cyclohexylamine and azetidine increases the solvatochromic (ICT) character, while this replacement in 2-(dimethylamino)ethyl-naphthalimide analogues
基于萘二甲酰亚胺的荧光团的光物理性质可以通过对该特权支架上的取代基进行化学处理而容易地调节。2-(羟基)乙基-萘二甲酰亚胺衍生物中第6位的OMe基被包括2-(羟基)乙胺,反式-(4-乙酰氨基)环己胺和氮杂环丁烷在内的多种胺取代,增加了溶剂致变色(ICT)特性,而这替换为2-(二甲基氨基)乙基-萘二甲酰亚胺类似物(PET荧光团)会降低其溶剂极性敏感性,甚至将其反转为溶剂变色荧光团。这些荧光团产生了巨噬细胞核成像探针,该探针结合DNA作为嵌入剂,并在人类癌细胞中显示出低细胞毒性。
