英文摘要	Compound 1 as an electron donor-acceptor compound with n,n-dimethylaniline and quinone units was designed for a highly selective colorimetric determination of thiol-containing amino acids and peptides, by making use of the unique reactivity of thiol towards quinone. compound 1 shows a strong intramolecular charge transfer (ict) band around 582 nm; but, it decreased after addition of either cysteine (cys) or glutathione (gsh). moreover, the ict band intensity at 582 nrn decreased linearly with the increasing concentrations of cys or gsh. the interference from other amino acids can be neglected. therefore, compound 1 can be employed as a selective colorimetric visual chemosensor for thiol-containing amino acids and peptides.
