Theoretical study of charge transfer in styryl thiazilo quinoxaline dyes STQ-1, STQ-2, and STQ-3 in organic media system

الملخص EN

Charge transfer in styryl dyes STQ-1, STQ-2, and STQ-3 with organic media system has been studied theoretically depending on the Franck-Condon rule and continuum dielectric model.

The reorientation energies (eV) were evaluated theoretically depending on dipole momentum, dielectric constant, and refrective index n.

The rate constant of charge transfer has been calculated depending on the reorientation energy (eV), effective free energy, potential height barrier, and coupling coefficient.

A matlap program has been written to calculated the rate constant of charge transfer and other parameter.

The results of calculations show that STQ-2 dye is more reaction for charge transfer compare with STQ-1 and STQ-3 dyes.
