Design and Self-Assembly of Supramolecular Photonic Materials

这项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。五到十个卟啉的离散有序阵列将通过大环上的外环配体与金属中心的配位进行自组装和表征，具有合适的配位几何结构、互补的氢键分子识别基团和混合金属离子和氢键介导的方法。将制备一维、二维和三维的卟啉薄膜、聚合物和晶体，并开发新的方法来表征这些材料。此外，还将通过自组装来制备新的光子材料。教育活动的重点将是开发一门超分子化学课程，并努力面向高中科学推广。凭借这一教师早期发展(职业)奖，有机和高分子化学项目正在支持纽约州立大学亨特学院化学系查尔斯·M·德雷恩博士的研究和教育活动。德里恩教授将把研究重点放在新材料的合成和表征上。由五到十个卟啉组成的阵列将自组装，以评估这些材料的可能形成，通过非共价相互作用进行电子和能量转移的机制，以及自组装过程。有待评估的总体假设是，通过将正确的键合代码编程到自组装单体中，可以系统地设计高度有序的光活性薄膜、聚合物和晶体。该项目的教育活动包括课程开发和接触高中生。

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.
