Stabilization of the borafluorene anion with carbenes

The incorporation of boron into polycyclic aromatic hydrocarbon systems leads to interesting chromophoric and fluorescing materials for optoelectronics, including organic light-emitting diodes (OLEDS) and field-effect transistors, as well as polymer-based sensors. A research team has now introduced a new anionic organoborane compound. Synthesis of the borafluorene succeeded through the use of carbenes.
