Abstract

A new version of reversible transformation of hydroxytricyanopyrrole (HTCP) chromophores is described. The process involves three-component reaction of 4-methyl-substituted HTCP, 2-hydroxy-5-nitro­benzaldehyde, and a base, which leads to the formation of ionic derivatives containing a phenolate fragment.
