An acceptor-donor-acceptor (A-D-A) triad based on a BODIPY acceptor and a benzodithiophene donor exhibited dual fluorescence and pronounced fluorescence solvatochromism because of twisted intramolecular charge transfer (TICT) state formation. Furthermore, it showed a Stokes shift of ∼194 nm which is the highest known for any BODIPY compound with a readily tunable fluorescence and a high charge carrier mobility of 4.46 × 10-4 cm2 V-1 s-1. © 2018 The Royal Society of Chemistry.
