Dendrimer metal core

Reinhoudt et al. also reported water-soluble pseudorotaxane-terminated dendrimers possessing a radio-active metal core for radiotherapeutical applications... 

Self-assembly of aromatic dendron subunits has been tried by the design of coordination to multivalent metal cations (i.e., metal-cored dendrimer complexes). Several metal-cored dendrimer complexes have successfully exhibited luminescence by antenna effects. 

Compound 12 is the largest photoactive dendrimer in which organic branches have been attached around a polypyridine metal core [29]. This dendrimer was obtained by reacting the metal precursor with a modified bpy carrying highly-... 

The oligo- or multi-functional core unit also plays a role in determining the space occupied by a dendrimer. The core itself can exercise a function, as demonstrated by metallodendrimers (see Section 4.1.11), in which the metal ion core in a supramolecular or coordinatively constructed architecture coordinates with the surrounding branching units - and in this way can influence catalytic and photochemical processes. 

Brunner et al. reported core-functionalised dendrimer metal catalysts ("dendri-zyme ) for use in enantioselective catalysis [lb, 10, 11]. Optically active dendrimer ligands were used, for example for the reaction of styrene with ethyl diazoacetate in a Cu(I)-catalysed enantioselective cyclopropanation. The starting compound for the preparation of these ligands was L-aspartic acid. However, (IS,2 S)-2-amino-1-phenyl-1,3-propanol can also serve as reactant for the synthesis of optically active dendrimer ligands.

Dendrimer 1 + is a classical example of a dendrimer containing a luminescent metal complex core. In this dendrimer the 2,2 -bipyridine (bpy) ligands of the [Ru(bpy)3] +-type core carry branches containing 1,2-dimethoxybenzene- and 2-naphthyl-type chromophoric units [15].
