Abstract
It is challenging to achieve room-temperature phosphorescence (RTP) in pure organics with both high efficiency and long lifetime. While much effort has been placed on discovering efficient phosphor skeletons, the importance of phosphor functionalization in enhancing the RTP performance has not received adequate attention. Herein, we demonstrate that functionalization of phosphors with sulfonic acid can ensure both bright and ultralong RTP, outperforming other substituents. The unique trigonal pyramidal structure of sulfonic acid group allows for more effective (n, π*) transitions to enhance intersystem crossing efficiency. Its highly polarized S–O bonds render strengthened hydrogen bonding interactions and a…
