Charge Transfer Molecular Complexes of Arylidene Anthranilic Acid Derivatives with  -Electron Acceptors.

Research Abstract

X-Benzylidenesanthranilic acid molecular complexes with π-acceptors, tetracyanoethylene, 2,3-dichloro-5,6-dicyano-p-benzoquinone and chloranil, have been studied. The intramolecular hydrogen bonding that exists in such compounds greatly inhibits the transition of the nitrogen azomethine n-electrons. The formation constant values and molar extinction coefficients of the p-dimethyl-aminobenzylideneanthranilic acid-DDQ CT complexes have been determined in CH2Cl2, C2H4Cl2 and CHCl3 in the temperature range 10-30oC. Such CT complexes are of strong n-π type
