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.

这项研究的重点是开发将卟啉构件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环外配体与金属中心的配位进行自组装和表征，并具有适当的配位几何形状、互补的氢键分子识别基团以及混合金属离子和氢键介导的方法。 将制备一维、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来制备。 教育活动的重点将是超分子化学课程的开发以及针对高中科学推广的努力。 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 教授将主要研究新材料的合成和表征。 五到十个卟啉阵列将被自组装，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，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对高中生的推广。
