A variety of anodically-coloring electrochromic molecules are provided. In particular, anodically-coloring electrochromic molecules and devices are provided that allow for tuning the absorption bands in the cation state across the visible spectrum while demonstrating little to no coloring or visible absorption in the neutral state, resulting in high-contrast devices. Electrochromic devices are also provided, as well as methods of making the devices and molecules, and methods of use thereof.
Direct C–H Arylation of Thiophenes at Low Catalyst Loading of a Phosphine-Free Bis(alkoxo)palladium Complex
An efficient phosphine-free direct C–Harylation of thiophenes at the α-position has been developed at low catalyst loading of bis(alkoxo)palladium complex (Cat.I, 0.1–0.2 mol %). The developed synthetic method can be applied to the synthesis of α-aryl/heteroaryl thiophenes from aryl or heteroaryl bromides in good to excellent yields and is compatible with the substrates bearing electron-donating or
