title: Asymmetric core-expanded aza-BODIPY analogues: facile synthesis and optical properties.
abstract: Significantly large Stokes shifts and enhanced solid state emissions were achieved in a novel series of asymmetric core-expanded aza-BODIPY analogues, 4a-4d, synthesized by a facile and scalable two-step reaction in high yields.
