title: Light harvesting and efficient energy transfer in dendritic systems: new strategy for functionalized near-infrared BF2-azadipyrromethenes.
abstract: A series of dendritic systems, which are capable of funneling energy from the periphery to the core, have been synthesized. The photophysical properties of the dendrimers, generations 0-2, have been determined. The light-harvesting ability of these compounds increases with increasing generation arising from the increase in molar extinction coefficient. Selective excitation of the donor leads to an efficient energy transfer (>90 %) to the acceptor. The approach provides a facile synthesis for modification of near-infrared BF2-Azadipyrromethene.
