Dual Excitation and Dual Emission in a 1,4‐Diazepine Bearing an Extended π‐System

Chemistry – A European Journal, Volume 31, Issue 50, September 5, 2025.
Cyclodehydrogenation of a previously reported nanographene BDI leads to the formation of a 1,4‐diazepine via scandium‐catalyzed C‐H bond formation. This compound exhibits a unique combination of dual excitation and dual emission. The dual emission was found to be caused by a combination of charge transfer and geometric relaxation in the excited state ...

A Mechanochemical Route for the Synthesis of Diphenyleneiodonium Salts and the Estimation of Their Relative Solid‐State Reactivities

Chemistry–Methods, Volume 5, Issue 9, September 2025.
An efficient mechanochemical route for diphenyleneiodonium (DPI) salt synthesis is reported which offers a sustainable and solvent‐free alternative. The solid‐state reactivities of the reported DPI salts were also assessed with the help of morphology predictions and Hirshfeld surface analysis computations to understand the effect of crystal morphology,
