Abstract
Second-order nonlinear optical properties are investigated for Langmuir-Blodgett (LB) films of charge-transfer complexes having non-centro-symmetrical molecular arrangements. The films exhibit large linear electro-optic effect (Im[χ(2)(-ω; ω, 0)] approx. 0.3 pm/V) in photon energy range of intramolecular transition, while component molecules have no permanent dipoles inside the molecules. The observed features in Im[χ(2)] spectra are discussed in terms of the electric-field-induced valence modulation effect on the intramolecular π-π* excitation of donor and acceptor molecules.
