Abstract

Second order nonlinear optical properties of C₆₀ based multilayered charge transfer structures with TPP, TPD and TPN molecules, acting as electron donors, are studied by the transverse optical second harmonic generation. The studied structures are of ABABAB...and ABCABC...type, where layer A is made from electron accepting molecules, layer B from electron donating and layer C from neutral molecules. The typical thickness of individual layers is about 2 nm. A significant increase of SHG is observed in ABCABC...type structures, where an effective charge transfer is expected with creation of a noncentrosymmetry in the perpendicular direction tot eh layers. The largest (chi) ⁽²) susceptibility is obtained with multilayers containing rubrene. The SHG generation experiments performed on thin films with different thicknesses show that the nonlinear optical response comes from the bulk material and not form the interfaces. A quadratic dependence of SHG intensity on input power is also observed, showing that the charge transfer takes place at the ground state.
