Popis:	A rhodamine-based fluorogenic probe bearing the quinaldine unit (L1) was developed as a turn-on fluorescent chemosensor for Cu2+. Upon binding with Cu2+, comparable amplifications of absorption and fluorescence signals were observed, which suggest that chemosener L1 effectively avoided the fluorescence quenching caused by the paramagnetic nature of Cu2+. Importantly, Li can selectively respond to Cu2+ over other commonly coexistent metal ions (such as K, Ca2+, Mg2+, Ni2+, Co2+, Fe2+, Fe3+, Hg2+, Zn2+, Cr3+) in aqueous media with a rapid response time (
