Monolayer terpyridyl metal complexes for high-efficiency electrochromic materials
Electrochromic materials (ECMs) can change their color with changes of applied electrochemical potential. Currently, the use of ECMs in the industry is limited to mainly inorganic metal oxides, conjugated conducting polymers, and liquid crystal-based materials. Hybrid metal-organic materials belong …
