Multidirectional Charge Separation in Self‐Assembled Aggregates of Perylenebisimide‐Porphyrin Bola‐Supra‐Amphiphiles

open access: yesAngewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Stable aggregates of a new hydrogen‐bond mediated porphyrin‐perylenebisimide (PBI) bola‐type supra‐amphiphile have been synthesized by lyophilization of solutions of both single molecules in THF/water mixtures, followed by redispersion in pure water. Cryogenic transmission electron microscopy verifies the spherical morphology.

Indium‐Free Recombination Junctions on Tunnel Oxide Passivating Contacts for Fully Textured Perovskite/Silicon Tandem Solar Cells

open access: yesSolar RRL, Volume 10, Issue 5, 12 March 2026.
We compare aluminum‐doped zinc oxide (AZO) and zinc‐doped tin oxide (ZTO) with indium tin oxide (ITO) as indium‐free transparent conductive recombination layers on textured TOPCon bottom cells for application in perovskite/silicon tandem devices. Sputter damage, passivation recovery, as well as optoelectrical material properties are studied.

Dual Chemical Looping/Catalytic Process for Alkylation of Benzene With Ethane and Propane Yielding Ethylbenzene and Cumene Over Copper‐Containing Mordenite

open access: yesAngewandte Chemie, Volume 138, Issue 10, 2 March 2026.
We report a dual chemical looping/catalytic process coupling alkane dehydrogenation with aromatic alkylation over Cu‐mordenite, yielding up to 25% alkylated aromatics with >95% selectivity per cycle. In situ NMR, FTIR spectroscopy, and DFT show alkylation proceeds via a π‐bound Cu(I)–olefin intermediate and Brønsted acid sites.

Sustainable Ammonia Electrosynthesis Coupled With Glycerol Valorization via an Adaptive Tri‐Component Catalyst

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 11, 9 March 2026.
A Cu‐Ni‐W tri‐component catalyst enables efficient nitrate‐to‐ammonia conversion under pulsed electrolysis. Combined experimental and theoretical studies attribute its performance to component synergism and regulated intermediates. Its facile adaptation for glycerol valorization to formic acid underscores a versatile system design concept, advancing ...

Chiral Potassium Brønsted Base‐Catalyzed Stereoselective Synthesis of 1,3‐Diols via a Tandem Allylic Isomerization/Asymmetric Aldol–Tishchenko Reaction

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 5, 3 March 2026.
Chiral potassium base catalysts featuring 1,1´‐bi‐2‐naphthol‐derived chiral crown ethers as ligands promote a tandem allylic isomerization/asymmetric aldol‐Tishchenko reaction of allylic alcohols and aldehydes. This method provides enantioenriched 1,3‐diols with excellent diastereoselectivity and high enantioselectivity, thereby expanding the synthetic
