Abstract

11,11,12,12-Tetrakis(4-methoxyphenyl)-1,4-diaza-2,3-diphenyl- and -1,4,5,8-tetraaza-2,3,6,7-tetraphenylanthraquinodimethanes (1 and 2) adopt a bent geometry. They undergo reversible redox interconversion with twisted dications 12+ and 22+, exhibiting a vivid change in color (electrochromism). Treatment with acid also induced drastic color change due to the formation of protonated species H-1+ and H-2+ (halochromism), thus demonstrating their two-way-input chromic behavior.
