项目摘要

pi-Conjugated organic materials are becoming the materials of choice for a number of high-tech optoelectronic applications, including displays, solar cells, memories, sensors, etc. Our ability to understand and to rationally design the electronic function in such materials is of paramount importance for development of future energy & information technologies, sensors, medical diagnosis, etc. Most of the special electronic properties in organics are enabled by highly delocalized electrons in conjugated organic molecules (pi-functional materials). Our research program is set to develop new approaches to synthesis and self-assembly of the new pi-functional materials, in order to control their electronic properties at the molecular and supramolecular level, and take advantage of these properties in device applications. Performing the studies at three different levels - individual molecules, self-assembled molecular films and covalent organic frameworks, we look for a generalized understanding of how electronic conjugation and intermolecular interactions control the transport of electrical charge through organic matter, and how to apply these properties to build functional optoelectronic devices. The research program for the next 5 years is focused on (i) development of novel emissive semiconductors based on fused oligopyrrole building blocks; (ii) development of bulk-heterojunction photovoltaic materials by hydrogen-bonding control self-assembly of donor and acceptor semiconducting molecules; (iii) development of conjugated covalent organic frameworks as highly robust electronic materials with strong electronic coupling and efficient charge transport properties.We expect that performing the suggested research will significantly impact our knowledge at the interface of organic chemistry, solid state physics and thin-film electronics, and yield the materials of practical importance for the optoelectronic technologies.

π-共轭有机材料正在成为许多高科技光电应用的首选材料，包括显示器、太阳能电池、存储器、传感器等。我们理解和合理设计此类材料中电子功能的能力至关重要对于未来能源和信息技术、传感器、医疗诊断等的发展具有重要意义。有机物中的大多数特殊电子特性是由共轭有机分子（π功能材料）中的高度离域电子实现的。我们的研究计划旨在开发新的π功能材料的合成和自组装新方法，以便在分子和超分子水平上控制其电子特性，并在器件应用中利用这些特性。通过在三个不同层面（单个分子、自组装分子膜和共价有机框架）进行研究，我们寻求对电子共轭和分子间相互作用如何控制电荷在有机物中的传输以及如何应用这些特性的普遍理解构建功能性光电器件。未来 5 年的研究计划重点是 (i) 开发基于熔融低聚吡咯结构单元的新型发射半导体； (ii) 通过施主和受主半导体分子的氢键控制自组装开发本体异质结光伏材料；（iii）开发共轭共价有机框架作为高度鲁棒的电子材料，具有强电子耦合和高效的电荷传输特性。我们预计，进行建议的研究将显着影响我们在有机化学、固态物理和薄膜领域的知识电子学，并产生对光电技术具有实际重要性的材料。
