Design and Self-Assembly of Supramolecular Photonic Materials

本研究的重点是开发将卟啉构建块组装成多组分阵列和材料的方法。由5到10个卟啉组成的离散有序阵列将被自组装，并利用大环上的外环配体与具有适当配位几何形状的金属中心的配位、互补的氢键分子识别基团以及金属离子和氢键介导的杂化方法进行表征。将制备一二维和三维卟啉薄膜、聚合物和晶体，并开发表征这些材料的新方法。此外，新的光子材料将通过自组装制备。教育活动的重点将是开发一门超分子化学课程，并努力与高中科学推广相结合。通过这个教师早期发展（CAREER）奖，有机和大分子化学项目支持了纽约市立大学亨特学院化学系Charles M. Drain博士的研究和教育活动。Drain教授将把研究重点放在新材料的合成和表征上。将自组装5 - 10个卟啉的阵列，以评估这些材料的可能形成，通过非共价相互作用的电子和能量转移机制以及自组装过程。要评估的总体假设是，高度有序的光活性薄膜、聚合物和晶体可以通过将正确的键合代码编程到自组装单体中来系统地设计。项目中的教育活动包括课程开发和面向高中学生。

The focus of this research is the development of methods for the assembly of porphyrin building blocks into multi-component arrays and materials. Discrete, ordered arrays of five to ten porphyrins will be self-assembled and characterized using coordination of exocyclic ligands on the macrocycle to metal centers with appropriate coordination geometry, complimentary hydrogen bond molecular recognition groups and a hybrid metal ion and hydrogen bond mediated approach. One- two- and three-dimensional porphyrin films, polymers and crystals will be prepared and new methods developed for the characterization of these materials. Also, new photonic materials will be prepared via self-assembly. The focus of the educational activities will be the development of a course in supramolecular chemistry and efforts geared to high school science outreach. With this Faculty Early Development (CAREER) award, the Organic and Macromolecular Chemistry Program is supporting the research and educational activities of Dr. Charles M. Drain of the Department of Chemistry at CUNY Hunter College. Professor Drain will focus his research efforts on the synthesis and characterization of new materials. Arrays of five to ten porphyrins will be self-assembled to evaluate the possible formation of these materials, the mechanism of electron and energy transfer via non-covalent interactions and the process of self-assembly. The overall hypothesis to be evaluated is that highly ordered photo-active films, polymers and crystals may be systematically engineered by programming the correct bonding code into self-assembling monomers. The educational activities in the project include course development and out reach to high school students.
