Two series of multi-cascade scaffolds bearing a boradiazaindacene (yellow dye) or a boradibenzopyrromethene (green dye) as the final energy acceptor have been synthesized. Each scaffold contains one, two or three alkynylaryl energy donors (such as pyrene D(1), perylene D(2), and fluorene D(3)) linked to the boron center. Palladium-catalyzed cross-coupling of dihalogenated Bodipy starting material enabled the step-by-step construction of the different modules. In all cases, selective irradiation in each absorbing subunit resulted in efficient energy transfer over 25 angstrom to the Bodipy units. (c) 2008 Elsevier Ltd. All rights reserved.

A multicomponent cluster has been synthesised in which four disparate chromophores have been covalently linked through a logical arrangement that favours efficient photon collection and migration to a terminal emitter. The primary energy acceptor is a boron dipyrromethene (Bodipy) dye and different polycyclic aryl hydrocarbons have been substituted in place of the regular fluorine atoms attached to

Taking the high road: Highly efficient electronicenergytransfer takes place from a set of appended aryl polycyclic hydrocarbons to an expanded borondipyrromethene (Bodipy)‐based dye (see figure) despite negligible spectral overlap with the lowest‐energy excited state localised on the acceptor.
