Near-Resonant Properties of Nonlinear Organic Materials for Optical Devices

摘要

The nonlinear optics of sublimated films of 2-dimensional conjugated planarmolecules has been investigated by third harmonic generation. Two were planar phthalocyanines, metal-free and copper substituted, and the third was an asymmetric (non-planar) phthalocyanine (subphthalocyanine), employed as a precursor in the synthesis of certain phtalocyanines. A very rich spectrum has been observed in each case and the analysis is currently underway. In the future this work will be expanded to include other materials.
