Au42(PET)32 Nanocluster Sensitizer Unlocks the Annihilator Potential of Rubrene, Enabling High‐Performance NIR‐to‐Visible Photon Upconversion

Angewandte Chemie, EarlyView.
A needle‐shaped gold nanocluster, Au42(PET)32, serves as a powerful triplet sensitizer, enabling rubrene to fully express its intrinsic annihilator capability (spin statistical factor f = 0.58). This sensitizer–annihilator pair achieves record‐high upconversion internal quantum yields of 21.4% (808 nm excitation) and 15.0% (936 nm excitation ...

Intramolecular Charge‐Transfer Dopants Enable Isolated Triplet Excitons as Spin Qutrits in a Single Crystal

Angewandte Chemie, EarlyView.
Photoexcitation of an intramolecular charge‐transfer molecule doped into single crystals of a structurally similar host molecule results in well‐ordered, spectrally addressable, and orientation‐tunable triplet excitons that maintain coherence at elevated temperatures.

Photochemical Cyclization of Tertiary Buta‐2,3‐dienamides to β‐Lactams Upon Triplet Energy Transfer

Angewandte Chemie, EarlyView.
Energy transfer is the key to the successful photocyclization of the title compounds to 3,4‐disubstituted 2‐azetidinones. If the substituent at the nitrogen atom is primary (R2 = H), trans products are formed exclusively. The triplet state of xanthen‐9‐one (XT) was found to be quenched by an allene amide (R, R2 = H, R1 = Bn, and R3 = Ph) with a ...
