Catching a plane: A new strategy for stabilizing the B[BOND]C bonds in boron-containing π-conjugated materials has been demonstrated. Encasing the boron in a rigid, planarized environment (see scheme) has been shown by Yamaguchi and co-workers to give air- and moisture-stable organoboranes that bring the boron's p orbital into full conjugation with the organic π framework.
