Valence Threshold Photoionization Spectra of C $_5$ H and C $_5$ H $_2$ Isomers. [PDF]

Chemphyschem
Mass‐selected threshold photoelectron spectra (TPES) of l‐C5H, HC5H, and c–C3H‐CCH were recorded using double‐imaging photoelectron‐photoion coincidence spectroscopy. These transient species were generated in situ by hydrogen abstraction from cyclopropylacetylene and 1,3‐pentadiyne.

Elucidating the Transition Kernel and Anharmonic Coupling in the Spin‐crossover Process of a [FeIII(qsal)2] CH3OSO3 Complex

Angewandte Chemie, EarlyView.
Ultrafast broadband transient absorption spectroscopy and multireference excited‐state nonadiabatic calculations in an open‐shell Fe(III) complex unveil the rich electronic and vibrational dynamics detailing the key reactive modes driving the spin‐crossover process.

Luminescent Donor‐Acceptor Radical With Propeller Chirality: Bright and Photostable Red Circularly Polarized Luminescence and Whispering Gallery Mode Resonance

Angewandte Chemie, EarlyView.
A series of donor‐attached brominated chiral luminescent radicals (CzTTBrM, 2CzTTBrM, and 3CzTTBrM) was synthesized, showing red to near‐infrared (NIR) circularly polarized luminescence (CPL) with exceptionally high PLQY of up to 76% and markedly enhanced CPL brightness (BCPL). Doping into polystyrene microspheres further yields whispering gallery mode

Highly Efficient Mechanochromic Thermally Activated Delayed Fluorescence in the Deep Red to Near‐Infrared in Copper(I) [2.2]Isoindolinophanyl‐Carbene Carbazolates

Angewandte Chemie, EarlyView.
Electrophilic [2.2]isoindolinophanyl‐based carbene iPC has been employed as charge‐transfer acceptor ligand in a series of [Cu(iPC)(carbazolate)], which show mechanochromism and environment‐dependent luminescence due to intermolecular C─‐H‐π interactions.

Conformational Landscapes in the Ground and Excited States Dictate Circularly Polarized Excimer Emission: A Thermodynamic–Kinetic Interplay in Carbazole Dimer Systems

Angewandte Chemie, EarlyView.
Covalently linked carbazole dimers exhibit intense excimer‐based circularly polarized luminescence (CPL). A simple propylene‐tethered dimer achieves glum ≈ 0.01 in the violet region—among the highest for small organic emitters without heavy atoms. Conformational mapping reveals CPL is governed by thermodynamic/kinetic control of emissive conformers ...
