Surface Coordination and Polymerization of Allyl Mercaptan Passivates the Oxidation of Copper
Advanced Materials Interfaces, EarlyView.This study demonstrates that allyl mercaptan self‐assembles on the surface of copper via coordination and polymerization, forming an ultrathin polymeric passivation layer (8.06 ± 0.50 nm). The modified copper foil achieves a two‐order‐of‐magnitude anti‐corrosion performance enhancement across multi‐service environments. Abstract The oxidation of copper

Thermally Stimulated Luminescence and Current in new heterocyclic materials for Organic field transistors and organic light emitting diodes [PDF]
arXiv, 2007 The present work is focused on theoretical and experimental study of localised levels in organic materials suitable for light-emitting devices and field effect transistors by means of thermal techniques. In our work we focused on low molecular compounds as well as on polymers, especially of two classes of materials: oxadiazoles and quinoxalines.

Advanced Optical Materials, EarlyView.Complexes [PtII(Cbz‐C^C*bzim/im)(L^L)], bearing carbazole‐appended cyclometalated NHCs, show bright phosphorescence, peaking from the blue to the yellowish–green spectral range depending on the carbene, L^L, and doping concentration. Non‐doped OLEDs using 1A or 3A (L^L = acac or P^O2) reach the best performances (Von: 2.99 V, 2.55 V; Lmax: 39208, 25837

Advanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.Abstract Photochemical C−C coupling reactions can be tailored to industrial chemical processes and preparations of pharmaceuticals. Recent approaches in this area are limited to using precious transition metal coordination complexes that facilitate light absorption and redox processes with benchtop chemicals. Herein, we propose a paradigm that involves
