Small, EarlyView.1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Small, EarlyView.Tunable nano‐twisted structures of novel isomeric macrocycles, which were controlled by cis/trans isomerizations of stiff‐stilbene units under light irradiations, have been exploited to modulate bent and planar configurations of 9,14‐diphenyl‐9,14‐dihydrodibenzo[a,c]phenazine (DPAC) moieties and adjust their ratiometric emissions. External factors, i.e.

Angewandte Chemie, Volume 138, Issue 46, 9 November 2026.Calderoselectivity is established as a stereochemical principle for sigmatropic rearrangements. A homoannulene‐based chiroptical photoswitch undergoes a photochemical [1,11] sigmatropic rearrangement with control of the acyl movement on top of the cyclic π system.

Oxidation of alcohols with pyridinium bromochromate
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1996 Pyridinium bromochromate (PBC) is a versatile and inexpensive oxidizing agent. It converts different classes of alcohols to the corresponding carbonyl compounds. Primary and secondary benzylic alcohols are oxidized in moderate to high yields. Synthetic utility of the reagent has been shown to increase in the presence of glacial acetic acid for the ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis
The Chemical Record, EarlyView.Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.
