Our {\\em ab initio} calculations for the neutral system reveal previously unknown stable 2D $\\epsilon$-B and $\\omega$-B structures. We find that the chemical bonding characteristic in this and other boron structures is strongly affected by extra charge. Beyond a critical degree of electron doping, the most stable allotrope changes from $\\epsilon$-B to a buckled honeycomb structure.
