Abstract
Abstract Molecular complexes of 2,3-dicyano-1,4-naphthoquinone with various aromatic anilines were studied spectrophotometrically in dichloromethane solvent at different temperatures. All these complexes show a new broad charge-transfer band in the visible region of the electromagnetic spectrum. All the donors are known to form strong 1:1 complexes with the acceptor and their stoichiometry was unaffected by the variation of temperature over a small interval. The thermodynamic and spectroscopic parameters were evaluated. The order of donor strength followed the sequence: 2,5-dimethylaniline > 2,3-dimethylaniline > N,N-dimethylaniline > p -toluidine > o -toluidine > m -toluidine > N-methylaniline > aniline.
