Abstract
A fluorescent off-on probe for H2S was exploited by coupling the azide-based strategy with the excited-state intramolecular proton transfer (ESIPT) sensing mechanism, which exhibits a considerably high fluorescence enhancement (1150-fold), an extremely low detection limit (0.78 nM), and a relatively fast response time (3-10 min) as well as excellent selectivity.
摘要
通过将基于叠氮化物的策略与激发态分子内质子转移（ESIPT）传感机制相结合，开发了一种用于检测硫化氢的荧光开-关探针，该探针具有相当高的荧光增强（1150倍）、极低的检测限（0.78 nM）、相对较快的响应时间（3-10分钟）以及出色的选择性。
