ESPRC-JSPS Core-to-Core Grant Application

九州大学有机光子学和电子学研究中心（OPERA）最近实现了具有高效热激活延迟荧光（TADF）的材料的创造。这种基于相对简单的芳香族有机化合物的新材料可以有效地将三重态激子转化为单线态激子，并迅速应用于有机发光二极管（oled）等光子器件中。从基本光化学和光物理学的角度来看，迫切需要更深入地了解这种独特的机制，在不需要稀有金属的情况下实现高效的系统间交叉。通过这个研究项目，与IDW Samuel教授（他的专长包括超快光谱学）、GA Turnbull教授（他的专长包括有机激光和化学传感器）、MC Gather教授（他的专长包括分子取向、光脱耦合效率和有机发光二极管在生物光子学中的应用）和E Zysman-Colman博士（他的专长是固态照明发光团的合成（包括TADF发射器））进行合作研究。圣安德鲁斯大学的教授（在EPSRC的支持下）和雷根斯堡大学的H Yersin教授（在BMBF的支持下），他在有机金属TADF发射器方面具有专业知识。Fabrice Mathevet博士（法国UPMC）的小组在CNRS的支持下和Ebinazar Namdas教授（澳大利亚昆士兰大学）的小组在澳大利亚研究理事会的支持下也将被纳入调查TADF排放者的国际联盟。该合作研究项目将侧重于基于量子化学计算和超快光物理分析的分子设计基础研究，同时也涉及设备开发和分析。通过来自日本、英国和德国的物理学家和化学家的合作，光学和器件特性的知识将反馈到分子设计中，通过这一过程的快速循环，新的有机半导体器件将被创造出来，同时也开发了人力资源，以推动下一代有机光电子学。为了促进合作和深化研究讨论，每月将通过视频会议召开研究会议，并由研究人员每半年访问参与组织。(2)每年举办一次研究研讨会，由三个参与国轮流主办，每个国家约10名研究人员聚集在一起进行生动的研究讨论。(3)此外，将通过派遣研究人员（研究生、博士后和/或助理教授）到参与组织进行为期3至6个月的人员和思想交流。此外，通过与福冈县和福冈市的联系以及与九州大学校园的邻近，OPERA计划与i3-OPERA（一个用于实际应用的有机光电子开发中心）和ISIT（系统，信息技术和纳米技术研究所）合作，并正在推进从基础到应用的有机光电子开发团队的研究，该团队由产业界-政府-学术界合作组成。与此同时，该项目将帮助在国际上建立这些组织，并以九州大学为中心。除了上述合作研究外，在器件实现方面，还将进行迫切需要的溶液处理研究，以及对TADF分子取向的控制。此外，将探索将TADF用于光放大和全新的应用，并解锁电泵浦有机半导体激光器和基于TADF的光催化剂的未来可能性。

The Center for Organic Photonics and Electronics Research at Kyushu University (OPERA) recently achieved the creation of materials exhibiting highly efficient thermally activated delayed fluorescence (TADF). The new materials, based on relatively simple aromatic organic compounds, can efficiently convert triplet excitons into singlet excitons and are quickly finding application in photonic devices such as organic light-emitting diodes (OLEDs). From a fundamental photochemistryand photophysics point of view, deeper understanding of this unique mechanism for highly efficient intersystem crossing without the need for rare metals is strongly desired.Through this research program, cooperative research with Prof. IDW Samuel, who has expertise including ultrafast spectroscopy, Prof GA Turnbull, who has expertise in organic lasers and chemical sensors, Prof MC Gather, whose expertise includes molecular orientation, light outcoupling efficiency and use of OLEDs for biophotonics, and Dr. E Zysman-Colman, who has expertise in the synthesis of luminophores for solid-state lighting (including TADF emitters), of the University of St. Andrews (with support from EPSRC) and Prof. H Yersin of the University of Regensburg, who has expertise in organometallic TADF emitters (with support from BMBF) will be undertaken. The groups of Dr. Fabrice Mathevet (UPMC, France) with support from the CNRS and Prof. Ebinazar Namdas (University of Queensland, Australia) with support from the Australian Research Council will also be integrated into the international consortium investigating TADF emitters. This cooperative research program will focus on basic research of molecular design based on quantum chemical calculations and ultrafast photophysics analysis while also tackling device development and analysis. Through the cooperation of physicists and chemists from Japan, the UK and Germany, knowledge of optical and device properties will feed back into molecular design, and through rapid cycles of this process, new organic-semiconductor devices will be created while also developing the human resources to drive the next generation of organic optoelectronics. To promote collaboration and deepen research discussion, monthly research meetings will be held via video conferences along with semi-annual visits by researchers to participating organizations. (2) Each year, a research workshop will be held, with the three participating countries rotating as host each year, and around 10 researchers from each country will gather for a lively research discussion. (3) Moreover, the exchange of people and ideas will proceed through the sending of researchers (graduate students, post-docs, and/or assistant professors) to the participating organizations for periods of 3 to 6 months.Furthermore, OPERA, through its connections with Fukuoka prefecture and city and its proximity to Kyushu University campus, has planned collaborations with i3-OPERA (a center for the development of organic optoelectronics for practical applications) and ISIT (The Institute of Systems, Information Technologies and Nanotechnologies) and is advancing research ranging from basic to applied with an organic optoelectronics development team formed through industrygovernment-academia collaborations. This program will at the same time help to establish these organizations internationally, with Kyushu University at the center. In addition to the mentioned cooperative research, with regards to realizing devices, investigations into solution processing, which is highly desired, and the control of the orientation of TADF molecules will be performed. Moreover, the use of TADF for light amplification and in brand new applications will be explored, and the future possibility for electrically-pumped organic-semiconductor lasers and TADF-based photocatalysts unlocked.
