Abstract:

The nonlinear optics of sublimated films of 2-dimensional conjugated planar molecules 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.
