A novel AIE active dual-channel coumarin derivatives, chemosensor G1, was synthesised and used for detecting Fe3+ (in water solution) in DMSO/H2O (1:9, v/v, pH = 7.2) binary solutions, which induced the colour of solution of G1 from yellow to shallow orange and increased the fluorescence emission, indicating that G1 could act as a corking colorimetric and “turn-on” fluorescence probe for detecting Fe3+. What’s more, sensor G1 has good anti-interference toward Ca2+, Hg2+, Cu2+, Ag+, Cd2+, Co2+, Ni2+, Mg2+, Pb2+, Zn2+ and Cr3+. Notably, the actual usage of sensor G1 was further demonstrated by logic gates and test kits.
