9529805 Pu Organic materials with second-order nonlinear optical properties are potentially very useful in optical information storage and processing, and in telecommunication. Three dimensional organic polymeric materials with similar NLO chromophore geometry are unknown. Organic polymers have better mechanical flexibility and processability than inorganic salts. We therefore propose to use optically active binaphthyls to build propeller polymers. These propeller polymers are expected to exhibit second-order NLO properties. The NLO properties of the propeller polymers can be adjusted and optimized by systematically modifying the conjugation length, the electron donors and acceptors of the repeat unit. Macroscopic organization of the propeller polymers will also be conducted by using ionic self-assembly technique. %%% This study will not only lead to potentially useful materials, but will also provide us the fundamental knowledge of these structurally fascinating new polymers. Potential implications are in the broad areas of electrical and electronic materials, thin-film devices, optical waveguides and similar active components. ***

~(9529805)Pu有机材料具有二阶非线性光学性质，在光信息存储和处理以及通信方面具有潜在的应用前景。具有相似NLO生色团几何结构的三维有机聚合物材料是未知的。有机聚合物比无机盐具有更好的机械柔韧性和加工性。因此，我们建议使用光学活性联萘来构建螺旋桨聚合物。这些螺旋桨聚合物有望表现出二阶非线性光学性质。通过系统地改变重复单元的共轭长度、电子给体和受体，可以调节和优化螺旋桨聚合物的非线性光学性质。螺旋桨聚合物的宏观组织也将利用离子自组装技术进行。这项研究不仅将带来潜在的有用材料，而且还将为我们提供这些结构上令人着迷的新聚合物的基础知识。潜在的影响涉及电气和电子材料、薄膜设备、光波导和类似的有源元件等广泛领域。***
