title: A boron-containing carbazole dimer: synthesis, photophysical properties and sensing properties.
abstract: A novel boron-containing π-conjugated compound  has been synthesized by the introduction of electron-acceptors (dimesitylboron groups) at the 3,3'-positions of a carbazole dimer (electron-donor). The compound  possesses excellent electrochemical properties and high fluorescence quantum yields. In addition,  is a sensitive fluorescence sensor with remarkable colour changes and the results could be confirmed through theoretical calculations of the compounds  and [(n)Bu(4)N](+)(2)[·(F)(2)](2-). Our studies indicate that  could be used as an excellent optoelectronic material in OLED devices and a ratiometric fluorescent chemosensor.
