Organic Optoelectronic Materials: Next Generation Semiconductors

设计共轭有机和聚合物材料将制备和评估作为光电子器件的有源层，特别是发光显示器（led），场效应晶体管（fet）和太阳能电池。将开发具有稳定蓝光发射的改进材料。先进的有机金属共轭聚合物将利用损失的三重态能量作为led的磷光，从而将潜在的设备效率提高到接近100%。fet中的活性层材料将具有改善的超分子有序性和可加工性，以提高电荷迁移率，而光伏材料将具有非色散空穴输运特性。塑料电子材料的图案沉积将使用一种涉及超临界二氧化碳的革命性沉积技术进行开发。

Designed conjugated organic and polymeric materials will be prepared and evaluated as the active layer in optoelectronic devices, particularly light emitting displays (LEDs), field effect transistors (FETs) and solar cells. Improved materials with stable blue emission will be developed. Advanced organometallic conjugated polymers will harness the lost triplet energy as phosphorescence in LEDs and so raise potential device efficiency in the vicinity of 100%. Active layer materials in FETs will have improved supramolecular order and processibility to improve charge mobility, while the photovoltaic materials will be developed to show non-dispersive hole transport properties. The patterned deposition of materials for plastic electronics will be developed using a revolutionary deposition technique involving supercritical carbon dioxide.
