中文摘要： 高效的能源利用来自于新型光电材料和器件的设计与开发。而有机低维晶态光电材料的易加工、高效发光效率和高电子迁移率等优势吸引了广泛的关注。如何设计和制备高效低维光电材料，探索高效电→光转换新机制，实现在激光光源、光通信、光显示等领域中应用，是一个具有挑战性的课题。在本项目中，我们拟以有机低维材料的分子设计与合成为基础，以微纳结构的可控制备为手段，考察分子结构、堆积方式、光电性能之间的关系，旨在揭示其内在调控机制并指导分子结构设计。重点研究基于光子限域作用的复杂光学波导、基于激子极化基元的极大曲率条件下光波导行为、低阈值光泵浦激光发射等，初步揭示低维材料的组成、形貌结构与光电性质的构效关系和内在调控机制。在设计并优化光电材料和器件性能的同时，以高效电→光转换为主要研究目标，探索电致发光器件诸如电泵浦纳米激光器等，开发新型高效的全光器件和纳米光源。

英文摘要： A key solution for the efficient use of energy is the design and development of new optical materials and devices. Organic low-dimension crystalline optoelectronic materials are paid more attentions due to their good processability, high luminous efficiency and high carrier mobility. A critical challenge is the design and fabrication of efficient low-dimension optoelectronic materials, the exploration of the mechanism of electro-optical conversion, and the application in the field of laser, optical communications, and displays. In this project, we will study the relationship among the molecular structures, stacked performance and optoelectronic properties based on the design and synthesis of organic molecules and controllable fabrication of the nanostructures. And their inner regulation mechanism and guidance the design molecular structures will be revealed. We will highlight photon confinement in the complex optical waveguide, exciton-polariton waveguide in the big curvature, and low threshold lasing emission, and so on. We will disclose that the relationship of the constitutions, morphologies and optoelectronic properties and interior modulation mechanism. Based on the above-mentioned studies, we will attempt to the optimization of optoelectronic materials and device performance, the study of the mechanism of
