CHARGE TRANSFER COMPLEXES BETWEEN SOME CRYPTANDSWITH TETRACYANOETHYLENE AND 2- HYDROXY-1,4-NAPTHOQUINONE

Abstract

ABSTRACT:The intermolecular charge transfer ( CT ) complex of two cryptands ,viz , K221 and K222 (as donors ) and tow acceptors, viz , tetracyanoethylene(TCNE) and 2-hydroxy-1,4-napthoquinon were studied ion Uv-visible region indichloromethane (DCM)as solvent at 298.2k .It was found that the basicity ofcryptand played an important role in the formation constant Kc value obtained .The nature of CT complexes formed were achieved by calculation of oscillatorstrength .
