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.***

9876027Tam-Chang 该项目的目的是通过关注系统中的结构-有序-性质关系（包括溶致相和薄膜中的两亲性苝双（二甲酰亚胺）），进一步了解固态有机材料的分子结构、分子间相互作用、分子有序和性质之间的关系。 将利用荧光光谱和偏振显微镜等技术研究薄膜的光学特性，如透射率、偏振效率、二向色比和荧光发射。 此外，通过在金上自组装单层烷硫醇获得的高度定制的表面将被用作界面模型，以研究分子取向和有序性对基底界面性质的依赖性。 教育目标包括为学生提供有机材料的研究机会，并通过修改本科课程内容引入固态有机材料化学问题来实施现有课程的变革，提供固态有机化学研究生专题课程，指导研究生（特别是少数族裔和女性），以及与专科学校教师合作将材料化学主题纳入普通化学课程。%%%有机新课程 与发展技术高度相关的材料正在迅速出现。 这些包括富勒烯和纳米管、有机超导体、光电导材料、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对学生进行培训，让他们在固态有机材料的开发和应用中发挥主导作用，从而为他们在重要的就业市场上有效竞争做好准备。***
