| Research Abstract |
At the first stage of this research project,we have focused our attention on the pi-conjugated polymer,polydiacetylenes. We established the fabrication technique of highly-oriented polydiacetylene films by vacuum deposition in 1987 [1],and extensively investigated the third- order nonlinear optical (NLO) properties of thus obtained films [1-4,10].
In the meantime, we developed the simple and accurate method for determining the third-order NLO susceptibility of thin films [6,7].
The research objects were extended to other polymers and low dimensional organic molecular crystals. The NLO properties of quasi- one-dimensional platinum compounds [5,8] and copper phthalocyanine [9] have been clarified.
The most important results were obtained for o-conjugated silicon polymer,polysilanes [11-14]. The modulus and phase of the complex third-order NLO susceptibility spectra were measured on the polysilane films over a wide photon energy range. From the analysis of the experimental results in terms of the one-dimensional exciton model, the important aspects of NLO processes of polysilanes are elucidated.
These researches were summarized in [15].
