报告摘要：

Organic optoelectronic materials have attracted increasing attentions owing to their high flexibility, low cost and facile preparation. To modulate optical and electrical properties of organic functional materials for high performance device applications, the excited states manipulation is of fundamental importance, promoting significantly the investigations and advances of organic electronics. In recent years, researchers including our group have benefited from introducing heteroatoms into conjugated systems to design and modify the excited states of organic functional materials. With the aid of heteroatom, which can interact effectively with the π-conjugated system via either lone-pair electron or empty orbital, excited states of the optolectronic molecules can significantly manipulated either statically and dynamically. For example, we found that singlet/triplet exciton formation ratio can be tuned to reduce quenching processes such as triplet-triplet annihilation and triplet-polaron quenching to realize higher efficiency and longer device lifetime. Incorporation of heteroatom-mediated resonance structure results in dynamically adaptive characteristics, which can selectively enhance electrical performance of organic semiconductors for high device performance. Combining with H-aggregation, the lifetime of luminescence was elongated from several nanoseconds to several seconds, which can be hardly achieved in conventional organic materials. In this talk, I will highlight recent advances in manipulating excited states of optoelectronic materials dynamically for various applications of OLEDs, bio-imaging, anti-counterfeiting and optical recording, paying special attentions on the mechanisms and photophysical processes.
