A naphthalimide-based bifunctional fluorescent probe for the differential detection of Hg2+ and Cu2+ in aqueous solution
摘要:
设计并合成了一种基于萘酰亚胺的新型荧光探针NPM。有趣的是,NPM在水溶液(10 mM HEPES,pH 7.5)中表现出对Hg2+的高选择性荧光开启和对Cu2+的高选择性荧光关闭。其荧光强度与Hg2+浓度呈线性增强,与Cu2+浓度呈线性降低。因此,NPM可用于水溶液中Hg2+和Cu2+的定量。为了探索NPM与Hg2+和Cu2+的传感机制和结合模式,我们合理设计并合成了一系列模型化合物。
available naphthalimide‐based fluorescent probe NPA for Pb2+ detection was successfully developed. NPA exhibited an obvious fluorescence turn‐on response toward Pb2+ in aqueoussolution and in livingcells. Moreover, a series of model compounds were rationally designed and synthesized in order to explore the sensing mechanism and binding mode of NPA with Pb2+.
