中文摘要： 以酞菁、偶氮、菁类等为代表的功能染料分子因其独特的分子结构特性而被广泛应用到材料学各领域。目前材料科学的发展对新型共轭结构分子有着大量的需求，因此新型功能染料分子的设计、合成及其结构与性能的关系研究已成为有机材料学领域的基本任务。本课题拟从不同的共轭体系、不同电子性能的取代基、不同的阴离子等角度设计合成芳杂环、中心阳离子结构、共轭双键等一系列具有电荷双向流动特征的高纯度阳离子染料，并以线性光学性能为基础，对其三阶非线性光学性能进行系统的研究；同时将性能优异的分子设计成单体，通过凝胶或聚合物旋涂成膜等技术进行成膜，对膜的形态和性能进行深入研究。通过该课题的研究，系统地获得上述高纯功能染料的合成与分离技术、热稳定性、吸收与发射光谱、三阶非线性光学吸收与折射、二阶超极化率等基本数据，以期望从中获取多个有应用前景并可调控设计的发色团，为高纯度功能染料分子的合成及其在光电材料领域的应用奠定基础。

英文摘要： Functional dyes, such as phthalocyanine, azo and cyanine, have been served as functional materials in several branches of material science. The design, synthesis and the structure-property relationship research of the new conjugated organic dyes have become the basic tasks in the organic material field. This project intends to design and synthesis of cationic dyes with bidirectional charge fluid ability, and aromatic heterocycles, central cationic structures and conjugated double bonds structures are chosen in this research. The results can be deduced from different conjugated systems, different substituent groups and different aspects of anions. Based on the synthesis and linear optical properties, third-order nonlinear optical properties of the dyes will be investigated. The monomer molecules of the potential candidates will be redesigned and converted to sol-gel hybrid materials and polymers, and the properties of the films, which will be obtained by spin coating, will be evaluated. The synthesis, purification, thermal stabilities, absorption and emission spectra, the third-order nonlinear optical absorption properties, the third-order nonlinear optical refraction properties and second hyperpolarizabilities of the functional dyes will be obtained. Several promising chromophores, whose structures can be regula
