title: Pyrrolopyrrole aza-BODIPY analogues: a facile synthesis and intense fluorescence.
abstract: Pyrrolopyrrole aza-BODIPY analogues were synthesized from diketopyrrolopyrrole and heteroaromatic amines in the presence of titanium tetrachloride. These novel compounds exhibit intense absorption in the visible region and strong emission with high fluorescence quantum yields greater than 0.8.
