The present investigation concludes that impregnation of malachite green, ferrocene in PVDF polymer matrix forms charge transfer complexes.Malachite green/ferrocene when doped in polymer may reside at various sides they may be substituted into the polymer chains or reside at the amorphous/crystalline boundaries and diffuse preferentially through the amorphous regions forming charge transfer complexes or they may exists in the form of molecular aggregates between the polymer chains. Malachite green has one amino group containing an unshared pair of electrons which may be responsible for CTC formation. The CTC are supposed to create localized states of various depths which will lead to trapping sides distributed over a considerably wide energy range. The formation of CTC considered reducing the barrier between the trapping sides providing a conducting path through the polymer matrix. The formation of CTC is usually characterized by the appearance of a new charged transfer bands in the spectra of the doped polymer as in the present case.
