Participation of the Halogens in Photochemical Reactions in Natural and Treated Waters
Molecules, 2017 Halide ions are ubiquitous in natural waters and wastewaters. Halogens play an important and complex role in environmental photochemical processes and in reactions taking place during photochemical water treatment.

Bulletin of the Korean Chemical Society, EarlyView.The development of organic solar cells (OSCs) has been driven by structural modifications of Y6‐series non‐fullerene acceptors. In particular, side‐chain engineering regulates solubility, molecular packing, and energy levels, enabling efficiencies to increase from 15.7% to over 20%.

BODIPY‐based J‐aggregates: From supramolecular chemistry to NIR bioimaging and phototherapies
Bulletin of the Korean Chemical Society, EarlyView.BODIPY dyes form ordered J‐aggregates through controlled supramolecular self‐assembly, producing narrow, red‐shifted absorption bands with small Stokes shifts. This review highlights design strategies governing J‐aggregation, structure–property relationships, and applications in sensing, bioimaging, and phototherapy, guiding functional BODIPY‐based ...

Synthesis and Reactivity of 3‐Aminosydnones in Cycloaddition Reactions With Alkynes
Chemistry – A European Journal, EarlyView.The synthesis, functionalization, and reactivity as dipoles of 3‐aminosydnones have been investigated. These neglected compounds undergo smooth cycloaddition reactions with strained alkynes, leading to 1‐aminopyrazoles. ABSTRACT We present in this article the synthesis, functionalization, and properties of 3‐aminosydnones, a forgotten class of ...

Chemistry – A European Journal, EarlyView.Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.
