- Abstract
Electron donor acceptor complexes (EDA) of the phenytoin sodium (Pyn) as a rich donor with different π-acceptors like p-chloranil ( p-CHL), 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), tetracyanoquinodimethane (TCNQ), chloranilic acid (CLA), N-bromosuccinimide (NBS) and picric acid (PA) have been synthesized. Spectroscopic and physical data such as formation constant ( K), molar extinction coefficient (ɛ), standard free energy (Δ G), oscillator strength ( f), transition dipole moment (μ), resonance energy ( R) and ionization potential ( I) have been determined. Based on the elemental analysis and photometric titrations the CT-complexes were found to have 1 : 1 stoichiometry.
