Dendrimers light-harvesting assembly

An extension of the present work has recently been published (30), in which a supramolecular system constituted by five Imni-nescent components, namely, one dendrimer 3, two Nd ions, and two molecular clips, have been assembled in solution with light-harvesting properties. [Pg.120]

The three components of the self-assembled structure have complementary properties so that new functions emerge from their assembly. Dendrimer 5 has a very high molar absorption coefficient in the UV spectral region because of 12 dimethoxybenzene and 16 naphthyl units, but it is unable to sensitize the emission of an Nd ion placed in its cyclam core. The [Ru(bpy)2(CN)2] complex can coordinate (by the cyanide ligands) and sensitize the emission of Nd ions. Self-assembly of the three species leads to a quite unusual Nd complex which exploits a dendrimer and an Ru complex as ligands. Such a system behaves as an antenna that can harvest UV to VIS light absorbed by both the... [Pg.131]
