开展有机晶态材料的制备、光电器件和集成的研究，其科学意义是十分清楚的。首先，有机晶态材料是促使有机电子学和晶体科学走向融合的关键和桥梁，具有联系有机电子学和晶体科学的天然优势。其次，有机晶态材料是通过分子堆积而成，可通过分子设计调控光电性能。再者，有机晶态材料，因为晶体内分子排列长程有序、无晶界、缺陷密度低，是揭示材料结构与性能的关系、构筑高性能光电器件的最佳选择。最后，有机晶态材料获取快捷，结合其可溶液加工、良好的柔韧性等特点，是突破现有有机电子学发展瓶颈，推动有机光电子材料与器件高效集成的关键。本项目针对“高迁移率有机晶态材料的可控制备及其光电器件的集成”开展研究，集中解决：(1) 高迁移率有机晶态材料的可控制备与光电性能调控问题；(2) 有机晶态材料的本征性能、光电响应与传输机制问题；(3) 有机晶态材料光电器件与集成的问题。

It is highly meaningful to carry out the study of organic crystalline materials, optoelectronic devices and circuits. First, organic crystals take the advantage to collect organic electronics and crystal science. Second, organic crystals depend on the molecular stacking, by controlling the molecular interactions we can tune the functions and properties of the crystals. Third, organic crystals have no grain boundaries, and low traps, which gives the promise to get devices and circuits with high performance. In this project, we will focus: (1) controllable production of organic crystals, (2) intrinsic properties of organic crystals, optoelectronic response and charge transport mechanism; (3) optoelectronic devices and circuits of organic crystals.
