Host‐Guest Doping Enables Room Temperature Phosphorescence from Triarylboranes
Angewandte Chemie, EarlyView.While pure triarylboranes show RTP in annealed PMMA films, they do not in crystalline form, contrary to our previous report. However, crystalline host‐guest triarylborane systems show persistent afterglow up to 8 s even at 1 ppb guest loading. Computations identify triplet‐triplet energy transfer as the mechanism governing this efficient RTP.
