The imidazole derivative 4-(4,5-diphenyl-1H-imidazol-2-yl)-N,N-dimethylaniline (probe 1) formed a highly coloured and non-emissive 1:1 stoichiometry complex with Cu(II) in water-acetonitrile 1:1 (v/v) solutions. Among all the amino acids (Lys, Val, Gln, Leu, His, Thr, Trp, Gly, Phe, Arg, Ile, Met, Ser, Ala, Pro, Tyr, Gly, Asn, Asp, Glu, Cys and Hcy) and tripeptides (GSH) tested, only GSH induced the...
Four imidazoquinolines functionalized with different carbocycles and heterocycles have been synthesized and characterized. Acetonitrile solutions of the four receptors presented absorption bands in the 330–370 nm range. The four probes were also emissive with fluorescence bands in the 390–460 nm interval. In a first step, the chromo-fluorogenic behaviour of the four probes was evaluated in the presence...
