Reduced and reoxidized : Thin films (100 nm) of tetrakis(thiadiazole)porphyrazine (see picture) are highly ordered in an unusual orientation of the molecular planes owing to the strong self‐assembling ability of these crystals. Electrochemical reduction of the thin films induces reversible electrochromism and n‐type carrier doping.
