Vibronic Trimer Design Enhancing Intramolecular Triplet‐Exciton Hopping to Accelerate Triplet‐Triplet Annihilation for Photon Upconversion

open access: yesAngewandte Chemie International Edition, EarlyView.
Triplet‐triplet annihilation‐based photon up‐conversion (TTA‐UC) system using an anthracene‐based UC emission by assembling multiple chromophores linked to a boron to enhance TTA rate constant. Structural fluctuations driven by vibronic motion induce picosecond intramolecular triplet exciton hopping, expanding the triplet exciton distribution and ...

Cyclo‐P5− Revisited: The Surprisingly Stable Uncoordinated Pentaphospholide Anion

open access: yesAngewandte Chemie International Edition, EarlyView.
The intriguing cyclo‐P5− anion, which is isolobal to the well‐known cyclopentadienide anion, was characterized for the first time crystallographically in the salts [M([2.2.2]cryptand)][cyclo‐P5] (M = Na, K). The compounds were further characterized by UV/Vis spectroscopy in solution and in the solid state by Raman and 31P MAS NMR spectroscopy ...

Reactivity of Pnictaalumenes towards 1,3‐Dipole Molecules

open access: yesAngewandte Chemie International Edition, Accepted Article.
Alkynes undergo 1,3‐dipolar cyclisation reactions with organic azides giving 1,2,3‐triazoles. Pnictaalumenes RPn=AlRˈ are the isoelectronic congeners of alkynes, hence a similar reactivity towards 1,3‐dipole molecules is expected. Herein, we report the reactions of DippTerPn=AlCp* (DippTer = 2,6‑(2,6‐iPr2C6H3)‐C6H3, Cp* = [Me5C5]−, Pn = P, As) towards ...
