Paper Abstract

Organic materials have received considerable attention because of their large dipole moments and optical nonlinearities. Organic materials for photonic applications contain chromophore dipoles consisting of acceptor and donor groups bridged by a delocalized π-electron system. Both calculations and experimental data show a reversible highly dipolar photoinduced intramolecular charge transfer in betaine type molecules and trans/cis photoisomerization in azobenzene derivatives, accompanied by change of the sign and the value of the dipole moment. The switching is important for optoelectronic effects including second harmonic generation. Arrangement of polar molecules in films is studied by surface potential measurements.
