9876027谭昌本项目的目的是进一步了解分子结构之间的关系，分子间的相互作用，分子顺序，和固态有机材料的性能，通过集中在系统中的结构-顺序-性能的关系，包括两亲性的perylenebis（二甲酰亚胺）在溶致相和薄膜。 将使用荧光光谱和偏振显微镜等技术研究薄膜的透射率、偏振效率、二色性比和荧光发射等光学性质。 此外，高度定制的表面获得的自组装单分子膜的烷硫醇在金将被用作模型的接口，以研究分子取向和秩序的依赖关系的基板的界面性质。 教育目标包括为学生提供研究有机材料的机会，并通过修订本科课程内容以引入固态有机材料化学问题，实施现有课程的改革，开设固态有机化学研究生专题课程，指导研究生（特别是少数民族和妇女），并与大专教师合作，将材料化学主题纳入普通化学课程。与发展中技术高度相关的新型有机材料正在迅速出现。 这些材料包括富勒烯和纳米管、有机超导体、光导材料、液晶和有机发光二极管材料。 通过良好的综合教学和研究计划培养学生，使他们能够在重要的就业市场中有效竞争，并通过教学在固态有机材料的开发和应用中发挥主导作用。

9876027Tam-ChangThe aim of this project is to further an understanding of the relationships between molecular structure, intermolecular interactions, molecular order, and the properties of solid-state organic materials by focusing on the structure-order-property relationships in systems to include amphiphilic perylenebis(dicarboximide)s in the lyotropic phase and in thin films. Optical properties such as transmittance, polarizing efficiency, dichroic ratio and fluorescence emission of thin films will be studied using techniques such as fluorescence spectroscopy and polarization microscopy. In addition, the highly tailored surfaces obtained by self-assembled monolayers of alkanethiolates on gold will be used as models of interfaces to study the dependence of molecular orientation and order on the interfacial properties of substrates. Educational goals include providing students with research opportunities in organic materials, and implementing changes in the existing curriculum by revising the content of undergraduate courses to introduce solid state organic materials chemistry issues, offering a graduate Special Topics course in solid-state organic chemistry, mentoring graduate students (especially minorities and women), and collaborating with junior college faculty to implement materials chemistry topics into the general chemistry curriculum.%%%New classes of organic materials that are highly relevant to developing technologies are rapidly emerging. These include fullerenes and nanotubes, organic superconductors, photoconducting materials, liquid crystals and organic light emitting diode materials. Training students through a well integrated teaching and research program prepares them to compete effectively in an important job market by teaching them to play a leading role in the development and application of solid state organic materials.***
