Selenanthrene with a folded geometry was used as a model to study the purely organic room-temperature phosphorescence (RTP) behavior under high pressure, and an unprecedented phenomenon of pressure-induced RTP enhancement was deeply studied.

An anthracene-based inter-excimer and intra-excimer were constructed, and their PLQYs can be ranked based on the environmental rigidity and excimer stability.

A functional unit combination strategy was proposed to achieve red room-temperature phosphorescence, in which the folded unit enhances spin–orbit coupling, while the benzo[c][2,1,3]thiadiazole unit dominates emission color.
