CAREER: Rational Design of Perfluoroalkylated N- and S-Containing Heteroaromatics for Engineering High Performance Air-stable OFET Materials with Lamellar pi-pi Stacked Structure

在化学系化学结构、动力学与机理B项目和材料研究部固体与材料化学项目的支持下，南达科他大学孙浩然教授将领导这一职业项目，目标是1)设计、合成和表征全氟烷基化的N-和S结构的杂芳族超分子合成子，以制备具有片状pi-pi堆叠结构的有机半导体材料；2)加深对分子结构、分子间弱非共价相互作用、固态结构和器件功能之间的关系的基本理解；以及3)培养学生解决材料科学中复杂问题的能力。孙教授的研究重点是这些全氟烷基化超分子合成子的合成和组装，用于低成本和高性能的下一代电子有机半导体器件。研究小组希望通过合成和计算两种方法来识别这些超分子合成子。在项目期间，不同级别的学生也将接受培训，学习解决材料科学问题的技能。该项目解决了开发下一代高性能有机半导体材料的基本问题之一：如何设计能够组装成所需功能材料的超分子合成子。对弱的非共价分子间相互作用的基本了解有望对新的有机功能材料的设计产生重大影响，并有助于新的药物设计。这个项目的多学科性质将为学生解决对当今材料化学重要的复杂问题提供极好的培训。除了这些激动人心的研究活动外，孙教授还将继续将尖端研究项目融入高等化学专业课程的本科教学中。该研究小组将与当地学校合作，为当地公众举办教育外展活动，包括为儿童举办的“郊狼科学教育”和“可再生能源研讨会”。研究和教育的成功结合将提供必要的劳动力发展，并使所有级别的学生培养解决与材料科学相关的社会问题的技能。

With the support from the Chemical Structure, Dynamics & Mechanisms B program in the Chemistry Division and the Solid State and Materials Chemistry program in the Division of Materials Research, Professor Haoran Sun at the University of South Dakota will lead this CAREER project aiming to 1) design, synthesize, and characterize perfluoroalkylated N- and S-containing heteroaromatic supramolecular synthons to prepare organic semiconductor materials with lamellar pi-pi stacked structure; 2) advance fundamental understanding of the correlation between molecular structure, weak intermolecular non-covalent interactions, solid-state structures, and device function; and 3) train students to solve complex problems in materials sciences. Professor Sun's research focuses on the synthesis and assembly of these perfluoroalkylated supramolecular synthons for low cost and high performance organic semiconductor devices for next generation electronics. The research team expects to identify these supramolecular synthons through both synthetic and computational approaches. During the project period, students at different levels will also be trained to learn skills for solving problems in materials sciences. This project addresses one of the fundamental questions in developing next generation high performance organic semiconductor materials: how to design supramolecular synthons that can assemble into desired functional materials. A fundamental understanding of weak non-covalent intermolecular interactions is expected to have substantial impact on new organic functional materials design and to assist new drug designs. The multidisciplinary nature of this project will provide excellent training to students for solving complex problems important to today's materials chemistry. In addition to these exciting research activities, Professor Sun will continue to integrate cutting-edge research projects into undergraduate teaching for advanced chemistry major courses. The research group will work with local schools to organize educational outreach activities including "Coyote Science Education for Kids" and "Renewable Energy Workshop" for general public in local areas. The successful integration of research and education will provide the necessary workforce development and prepare students at all levels to develop skills for solving societal problems related to materials sciences.
