ChemElectroChem, EarlyView.This concept outlines the mechanism of molecular‐level multi‐electron storage, leveraging the quantum properties of electrons in σ bonds. Effective through‐space interactions between the 2pz atomic orbitals of electrophilic centers in organic superelectrophores enable the formation of supra‐LUMOs with bonding character, capable of hosting electrons ...

The Effect of Regioisomerism on the TADF Properties of Organic Dyes
ChemistryEurope, EarlyView.The properties of TADF emitters are highly dependent on the chosen electron donor and acceptor, as well as the π‐system that links them together. Herein, we show that regioisomerism affects the physical properties of spirobifluorene‐based systems in solution, thin films and crystals.

Acetylation‐Deacetylation‐Driven Natural Product Biosynthesis
ChemistryEurope, EarlyView.This review summarizes the role of acetylation‐deacetylation in natural product biosynthesis, including acetylation followed by deacetylation after several biosynthetic steps, acetylation‐mediated rearrangement, acetylation‐triggered elimination, and the acetylation cycle as a regulatory mechanism. These processes are vital for the formation of complex
