Direct demonstration of triplet excimer in purely organic room temperature phosphorescence through rational molecular design

Light: Science & Applications, 2022
An ideal model containing eight phenothiazine 5,5-dioxide derivatives was established to clearly prove the formation of triplet excimer. Competition between monomer (T1) and excimer (T1*) based on π-π stacking is the origin for their changed RTP ...
