Charge-transfer molecular complexes of some 2-aryl-4-arylidene-5(4) oxazolanes with di- and trinitrobenzene have been studied at 25°C. The stoichiometry and apparent formation constants of the complexes formed were determined by applying the conventional continuous variation method. The role of the molecular structure of the electron donor and acceptor compounds as well as the nature of the solvent on the formation of such charge-transfer complexes. Furthermore, association constants, oscillator strength, dipole moment, and free energy are elucidated. |
