Thiourea inclusion complexes of organometallics: optically non-linear materials

Abstract Inclusion complexation of organometallics with thiourea has been found to be an effective mechanism for controlling bulk nonlinear optical properties by inducing molecular dipolar alignment. Structures of the thiourea inclusion compounds with (benzene) Cr(CO) 3 and (1,3-cyclohexadiene)Fe(CO) 3 have been achieved. These materials generate second-harmonic radiation when exposed to the 1.06 μm output of a Nd-YAG laser.

Guest-Host Molecular Ensembles for Nonlinear Optics

Abstract This paper discusses structural strategies for assembling bulk materials for nonlinear optics. In part one, we review a strategy, based on the concepts of guest-host inclusion complexation. We incorporate molecules into crystalline environments in which molecular dipoles are assembled into materials for second harmonic generation by polar alignment of the dipoles. In part two, we review the fabrication and properties of optical quality materials for third order nonlinear optics based on nanoscale particles of semiconductors included in polymer media.
