Abstract

Abstract: The Charge transfer(CT)complexes formed between N-arylmaleimides(RPhMI)as the acceptors and thiosulfate anion(S₂O₃^2-) as donor in 95% DMSO/H₂O were studied by UV-Vis spectroscopy.The electron affinities(EA)of RPhMI had been calculated from the CT spectra,And the formation constants(K)of the CT complexes were determined.The results indicate that weak acceptors,N-arylmaleimides could form stable CT complexes with the thiosulfate anion which acts as a strong donor,The possible structure of the CT complexes and the relationship of their stability and the substituent polarlity of RPHMI were discussed.

Key words: N-arylmaleimides, sodium thiosulfate, charge transfer complex, electron affinity
