摘要：

Seeing the light: Tuning the electron-donating ability of the π-conjugated framework of bithiophene has resulted in intense solid-state emissions with maxima ranging over a wide visible region (see picture). Even a deep-red fluorescence with a large Stokes shift close to 200 nm, arising from the intramolecular charge-transfer (CT) transition from the twisted bithiophene π framework to the boron center, can be obtained.
