Nonlinear Spectroscopy (absorption, refraction and their relation) of Organic Materials

本研究拟利用本研究组研制的专用分光光度计研究各种有机染料的非线性光学性质，例如酞菁和聚甲川染料、不对称芴基染料和聚二乙炔。 用这种方法研究了半导体和电介质材料的非线性光谱，其结果是很有用的。 最终的目标是发展一个预测能力的非线性光学性质的线性光学性质和/或有机材料的分子结构。

The proposed research is to study nonlinear optical properties of various organic dyes, e.g. phthalocyanine and polymethine dyes, asymmetric fluorene-based dyes and polydiacetylenes, by using a special spectrophotometer built by the group. The non-linear spectra of semiconductor and dielectric materials have been studied in the past by this technique, and the results are very useful. The ultimate goal is to develop a predictive capability for the nonlinear optical properties in terms of the linear optical properties and/or molecular structures of organic materials.
