Investigations done so far have shown that dopant material have a considerable effect on the electro-optical responses
of dye-doped liquid crystal. But the type of inter or intra-molecular interaction roles in electro-optical
properties and nonlinearity of doped liquid crystalline systems has uncovered. In this work, to study of the
kind of molecular interaction effects on electro-optical properties of doped LC, two dyes with dissimilar interactional
and functional groups were used as LC dopants. Therefore, doping these dyes into liquid crystals allows us
to understand and analyze the effect of interaction type on electro-optical responses of the pure and doped samples.
The electro-optical Kerr behavior, the pre-transition temperature and third order nonlinear susceptibility of
pure and doped LC by two dyes with different interactional groups were having studied
