Recent Advances in pi-Conjugated NC-Chelate Organoboron Materials

Boron-containing pi -conjugated materials are archetypical candidates for a variety of molecular scale applications. The incorporation of boron into the pi -conjugated frameworks significantly modifies the nature of the parent pi -conjugated systems. Several novel boron-bridged pi -conjugated materials with intriguing structural, photo-physical and electrochemical properties have been reported over the last few years. In this paper, we review the properties and multi-dimensional applications of the boron-bridged fused-ring pi -conjugated systems. We critically highlight the properties of pi -conjugated N<^>C-chelate organoboron materials. This is followed by a discussion on the potential applications of the new materials in opto-electronics (O-E) and other areas. Finally, attempts will be made to predict the future direction/outlook for this class of materials.
