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].

在该研究项目的第一阶段，我们将注意力集中在π共轭聚合物聚二乙炔上。我们于1987年建立了真空沉积高取向聚二乙炔薄膜的制备技术[1]，并广泛研究了由此获得的薄膜的三阶非线性光学（NLO）性能[1-4,10]。同时，我们发展了简单而准确的测定薄膜三阶非线性光学敏感性的方法[6,7]。研究对象扩展到其他聚合物和薄膜。 低维有机分子晶体。准一维铂化合物[5,8]和铜酞菁[9]的非线性光学性质已经得到阐明。最重要的结果是在邻共轭硅聚合物、聚硅烷[11-14]上获得的。在较宽的光子能量范围内测量了聚硅烷薄膜上复杂的三阶 NLO 磁化率谱的模量和相位。通过一维激子模型的实验结果分析，阐明了聚硅烷非线性光学过程的重要方面。这些研究总结于[15]。
