Recent research in the area of functional π-conjugated materials has shown that the incorporation of heteroelements - main group elements such as B, Si, Te, and P in particular - is an efficient strategy to obtain organic materials with value-added properties for a host of different practical applications.<br/>This presentation will highlight our efforts in designing viologen-inspired organophosphorus building blocks, and exploring their suitability for advanced functional materials, particularly with a focus toward highly sought-after electron-acceptor materials. Based on dedicated phosphorus-chemistry strategies, the materials can be fine tuned to reversibly stored up to three electrons. Similar to the parent viologens, the fully reversible redox events that are also accompanied by distinct color changes, enable the use in practical applications such as electrochromic devices and organic batteries.
