New chiral terpyridines containing Frechét-type dendrons have been readily synthesized by coupling dendritic benzyl bromide and 4‘-[6-(2,2‘-dihydroxy-1,1‘-binaphthyl)]-2,2‘:6‘2‘ ‘-terpyridine. These chiral dendritic terpyridines were used to efficiently construct high molecular weight hybrid metal−organic dendrimers based on the Ru(II)−bis(terpy) linkage. Preliminary fluorescence measurements show generation-dependent fluorescence quenching behavior of 3,5-dimethoxybenzyl peripherals by the [Ru(terpy)2]2+ unit.
