摘要

Novel two-dimensional conjugated systems have been developed for second- and third-order nonlinear optics. Four types of asymmetrically substituted macrocycles and non-aggregated phthalocyanines were synthesized and their second- and third-order nonlinear optical properties were characterized: meso-monosubstituted octaethyl metalloporphyrins, $beta@- monosubstituted tetraphenyl metalloporphyrins, mono (tert-butyl) vanadyl phthalocyanine, tris (tert-butyl) mononitro metallophthalocyanines, and hexadeca (trifluoroethoxy) metallophthalocyanines. Control of molecular packing in asymmetric vanadyl phthalocyanine was described in terms of the enhancement of the third-order nonlinear optical susceptibility. No evidence of molecular aggregation was observed in optical absorption and electroabsorption spectra for hexadeca (trifluoroethoxy) metal-free and vanadyl phthalocyanines. The effects of the substituents and metallation on the dipole moment for asymmetric porphyrins is discussed. A preliminary investigation of the second-order nonlinear optical responses for Z-type Langmuir-Blodgett films and poled molecularly doped polymer is presented.
