文摘

Thiazole-based probe 1 for sensing Ga3+ was synthesized. Ga3+ ions “switched on” the emission of probe 1. In situ generated 1-Ga3+ ensemble detected HP2O73–ions sequentially through “switch off” response. Fluorescence mechanism of 1 explained by inhibition of ESIPT and CHEF due to binding with Ga3+.
