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.

Double E─H Bond Activation of Ammonia and Water by Cyclic Gallaphosphene L(OCP)GaPGaL

Angewandte Chemie, EarlyView.
Cyclic gallaphosphene 1 undergoes a twofold E─H bond activation with ammonia and water via a beneficial interplay between the polar “GaPGa” unit and the electrophilic nature of the C center in the bridging PCO unit, yielding six‐membered heterocycles 2 and 3, in which both nucleophilic phosphorus atoms are protonated.

Mechanism of the Photodecomposition of Stable Triarylmethyl Radicals

Angewandte Chemie, EarlyView.
Photolysis of luminescent chlorinated trityl radicals was studied with density functional theory and the decomposition products were isolated and characterized. It proceeds by a 5‐electron electrocyclization then a 1,8‐sigmatropic chloride shift, forming non‐emissive, less stable fluorenyl radicals.
