Visible‐Light Mediated Activation of 1,3‐Dienes and Allenes via Energy Transfers

Chemistry – A European Journal, Volume 31, Issue 67, December 1, 2025.
Nature has inspired chemists to develop photocatalytic processes that harness visible light, offering alternative reaction pathways beyond traditional thermal methods. Energy Transfer (EnT) is a particularly promising strategy, enabling transformations such as isomerization, deracemization, cycloadditions, and cascade reactions.

Recent progress of heterocycle ring‐opening (co)polymerization for the synthesis of sequence‐controlled block polyesters and polycarbonates

Smart Molecules, Volume 3, Issue 4, December 2025.
Block copolymers are fundamental for the development of smart molecules. Aliphatic polyesters and polycarbonates have received attention as heteroatom‐containing polymers that are biodegradable and biocompatible. Block polymers from polyesters and polycarbonates have the ability to form smart molecules. This review presents the heterocycle monomer ring‐
