A series of four ullazine‐donor based donor–π bridge‐acceptor (D–π–A) dyes have been synthesized and compared to a prior ullazine donor‐acceptor (D–A) dye as well as a triphenylamine donor with an identical π–bridge and acceptor. The D–π–A ullazine series demonstrates an unusually uniform‐in‐intensity panchromatic UV/Vis absorption spectrum throughout the visible region. This is in part due to the
