A novel “turn-on” fluorescent probe for Fe3+ in aqueous media based on C
N isomerization†
Abstract
A new type of N isomerization was synthesized. It shows fluorescence enhancement (turn-on) response for Fe3+ in aqueous media (v(CH3CN) : v(H2O) = 1 : 9). The complexation mode and the corresponding fluorescent enhancement mechanism were elucidated by
