Chemistry – A European Journal, EarlyView.Europium doping of bismuth oxido nanoclusters (BiO‐NCs) provides stable hosts for Eu3+ in an asymmetric coordination environment, which in turn results in an intense 5D0→7F0 transition and long luminescence lifetimes. Transparent hybrid materials showing characteristic red photoluminescence are accessible via radical copolymerisation of these soluble ...

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles
European Journal of Organic Chemistry, EarlyView.Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

π‐Extended Silyl Enolates as Emerging Platforms in Radical Chemistry
European Journal of Organic Chemistry, EarlyView.This review covers the emerging role of π‐extended silyl polyenol ethers in radical chemistry. It highlights their versatile roles as electron‐rich SOMOphiles, silyl radical cation precursors, and nucleophilic partners in radical–polar crossover manifolds, while considering recent advances in photoredox catalysis, electrochemistry, and transition metal‐
