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.

PI结合的有机材料正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，记忆，记忆，传感器等。我们理解和合理设计这种电子功能的能力至关重要分子（PI功能材料）。我们的研究计划旨在开发新的PI功能材料合成和自组装的方法，以控制其电子性能在分子和超分子水平上，并在设备应用中利用这些特性。在三个不同级别上进行研究 - 单个分子，自组装的分子膜和共价有机框架，我们寻求对电子结合和分子间相互作用如何控制电荷通过有机物的传输以及如何施加这些特性来构建功能性光电磁性设备的广泛理解。未来5年的研究计划集中在（i）基于融合寡吡咯的构建基础的新型发射半导体的开发； （ii）通过氢键控制供体和受体半导体分子的氢键控制自组装来发展散装型光伏材料； （iii）开发共轭的共价有机框架作为具有强大的电子耦合和有效的电荷传输属性的高度稳健的电子材料。我们希望，我们在有机化学，固态物理学和薄膜电子学的界面上进行建议的研究将极大地影响我们的知识，并产生对光学技术的实用重要性的材料。
