Abstract
A series of novel Lewis base monoadducts of 9-bromo-9-borafluorene (BrBFl•LB, LB = IPr, IPrCH2, PPh3) and the bisadduct [(DMAP)2BFl]Br were prepared and underwent reactivity studies in the pursuit of incorporating a borafluorene unit into a polymeric scaffold for the sensing of nucleophiles in solution. This was to be accomplished through the functionalization of these adducts at boron, polymerization and subsequent removal of the Lewis base. Although initial studies indicated that the removal of the Lewis base was more difficult than anticipated, the adducts BrBFl•PPh3, [(DMAP)2BFl]Br and BrBFl•IPrCH2 were found to be fluorescent. This observation was initially counterintuitive, as a borafluorene containing a four-coordinate boron environment would not be expected to possess such a property. Theoretical studies were conducted to determine the nature of the fluorescence and revealed that the Lewis base bonded to boron significantly contribute to the transitions leading to fluorescence.
