I came across this article on electrochomic displays. It mentions Ethyl Viologen as an electochromic chemical. I would like to attempt an experiment to showcase it's electrochomic properties but don't really know where to start.
Second, what to do with it once I have it? I take it there's more to it than just sticking some electrodes in a beaker of it.
The article states, "If the EV-molecule absorbs a second electron, EV turns pale blue. This reduction however is irreversible and definitely not wanted." What care (if any) do I need to take to avoid this?
Sorry if I ask something obvious, I'm very inexperienced with chemistry.
