摘要：
2-(2-methoxyphenyl)-4,5-diphenyl-1H-imidazole 1, an imidazole-based compound, was found to sense Cu2+ ions via fluorescence and absorption spectroscopy over a number of other metal ions. During Cu2+ sensing, the chemosensor 1 followed a "switch-off" mechanism. Job's plot supported 1:1 stoichiometry of 1-Cu2+ complex. The 1-Cu2+ complex formed in situ underwent different absorption changes with OH- ions. These differential absorption changes observed with the addition of Cu2+ and OH- ions were used to mimic AND logic gate using A(274nm) as output.
