Nonreaction-based fluorescent Au~(3+) probe that gives fast response in aqueous solution

摘要

The design and synthesis of a simple, selective and efficient turn-off fluorescent Au~(3+) probe, namely, diethyl 1-phenyl-2,5-di(thiophen-2- yl)-1H-pyrrole-3,4-dicarboxylate (1), are highlighted. To our best knowledge, this is the first example of nonreaction-based fluorescent Au~(3+) probes.
