Efficient Semitransparent Organic Solar Modules with Exceptional Diurnal Stability Through Asymmetric Interaction Induced by Symmetric Molecular Structure

Angewandte Chemie, EarlyView.
The symmetric molecular structure of 4FY has been shown to induce an “asymmetric molecular interaction”, which promotes a higher degree of molecular packing than in Y6. The asymmetry‐driven molecular interactions can be leveraged to fabricate large‐area semitransparent organic solar modules that are efficient and stable under realistic operating ...

Li21Ge8P3S34: New Lithium Superionic Conductor with Unprecedented Structural Type

Angewandte Chemie, EarlyView.
The discovery of high ion‐conductive inorganic crystal structures remains a challenge in facilitating the development of all‐solid‐state batteries. Ionic conductors reported to date have predominantly been limited to well‐known crystal structures. In this work, we report a new, unprecedented crystalline structure, Li21Ge8P3S34, which demonstrates high ...

Enantioselective Photochemical Generation of a Short‐Lived, Twisted Cycloheptenone Isomer: Catalytic Formation, Detection, and Consecutive Chemistry

Angewandte Chemie, EarlyView.
In a proof‐of‐concept study, it was for the first time shown that planar chiral trans‐cycloalk‐2‐enones, such as 2, can be formed enantioselectively from their cis‐isomers by triplet energy transfer from a chiral catalyst. Computational studies performed with cyclohept‐2‐enone and enone 1 provided invaluable insights into the mode of action of the ...

π‐Extended Heli(aminoborane)s with Highly Bright Circularly Polarized Luminescence and Narrowband Emission

Angewandte Chemie, EarlyView.
Three π‐extended heli(aminoborane)s (E[10]HAB‐A/B/C) were synthesized to find a balance between fluorescence quantum yield (Φlum) and absorption/luminescence dissymmetry factors (gabs/glum). These molecules exhibited remarkable photophysical properties, including high Φlum and narrowband emission (full width at half maximum, FWHM=16 nm), in which E[10 ...

Photogeneration and Visualization of a Surface‐Stabilized Dinitrene

Angewandte Chemie, EarlyView.
In this communication we report the formation of a stable, surface‐supported dinitrene achieved through the photolysis of a diazide precursor on an Au(111) metal substrate. We combine high‐resolution scanning probe techniques with theoretical calculations, providing the first real‐space imaging of a metal nitrene adsorbed on a surface and exploring the

B ← N Lewis Pair Fusion of N,N‐Diaryldihydrophenazines: Effect on Structural, Electronic, and Emissive Properties

Angewandte Chemie, EarlyView.
B─N Lewis pair fusion of N,N‐dipyridyldihydrophenazine and its benzofused homologs results in steric constraints that enforce a bent structure in both the ground and excited states, reduces the antiaromatic character of the central dihydropyrazine heterocycle and promotes a quinoidal resonance structure, bathochromically shifts the absorption and ...
