Novel Molecular Semiconductors for Optoelectronic Applications: Photophysics and Devices

本研究项目致力于新型有机半导体的研究，探索不同的光物理机制，以促进新材料在能够在光或电激励下工作的发光器件中的应用。复杂的光物理机制将被研究，包括具有环状结构的化合物中的热激活延迟荧光的研究，D-A-D化合物中携带三重施主并将能量转移到单重受主的能量转移，以及具有增强的自旋-轨道相互作用的新型分子结构，以促进在深红色和近红外区的有效发射。研究工作包括研究溶液和固态薄膜随温度的变化，使用稳态和时间分辨光学光谱技术，以及制作电致发光二极管。学生将利用无尘室设施获得先进的光谱学技术和器件制造方法方面的广泛培训，并将有机会通过参加我们的研究生课程和研讨会来巩固物理和化学的基本概念。

This research project is focused on the investigation of novel organic semiconductors, exploring different photophysical mechanisms to promote the application of new materials in light emitting devices that are able to work under optical or electrical excitations. Complex photophysical mechanisms will be investigated, including the investigation of thermally activated delayed fluorescence in compounds with cyclic structures, energy transfer in D-A-D compounds that carry triplet-donors and transfer energy to a singlet-acceptor, and novel molecular structures with enhanced spin-orbit interactions to promote efficient emission in the deep-red and near-infrared regions. The research work involves studies in solution and solid state films as a function of temperature, using steady-state and time-resolved optical spectroscopy techniques, and fabrication of electroluminescent diodes. The student will acquire extensive training in advanced spectroscopy techniques and device fabrication methods using clean-room facilities, and will have the opportunity to consolidate fundamental concepts in physics and chemistry by attending our postgraduate courses and seminars along the project.
