A series of novel mono- and di-substituted -n-butyl-1,8-naphthalimide derivatives were synthesized simultaneously via a three-step reaction. The single crystal structure of -n-butyl-4-[','-bis(2',4'-dichlorobenzoyl)ethylamino]-1,8-naphthalimide () was determined. The UV-vis and fluorescence properties of compound were investigated. The showed highly selective and sensitive fluorescence changes response towards Pb. A titration of monomer with Pb ion was performed. When Pb ion concentration increased from 0 to 10 eq., the fluorescent intensity of decreased from 199.97 to 48.21. The pH effect on showed that it is stable in a wide range of pH. The results indicated that might be a probe molecule for Pb.
通过三步反应，同时合成了一系列新型的单取代和二取代的正丁基-1,8-萘酰亚胺衍生物。确定了 -n-丁基-4-[','-双(2',4'-二氯苯甲酰基)乙氨基]-1,8-萘酰亚胺 ()的单晶结构。研究了化合物 的紫外可见和荧光性质。显示出对 Pb 具有高度选择性和灵敏的荧光变化响应。对单体与 Pb 离子进行了滴定。当 Pb 离子浓度从 0 增加到 10 eq.时，的荧光强度从 199.97 降低到 48.21。对 的 pH 效应表明，它在很宽的 pH 范围内稳定。结果表明，可能是 Pb 的探针分子。
