Abstract

We prepared the nonlinear optical heterocyclic chromophores that show fairly high microscopic nonlinearity through intramolecular charge transfer. Phenothiazine and carbazole units played an important role to contribute fairly high electron donability and connect the resonance pathway via conjugative effect in the cyclized ring beside the aromatic ring. Electro-optic (EO) properties of the guest-host systems in amorphous polycarbonate containing the synthesized gradient bridge chromophores with the same concentration were investigated under identical poling conditions. Real time pole and probe method gave us much more information how the electro-optic properties can be brought about and can be optimized.
