The selective use of
tert-butoxycarbonyl protecting group chemistry has enabled efficient
syntheses of multilinked macrocyclic derivatives incorporating tetraaza
and aza-thia donor rings. Mixed ring species have also been prepared as
well as a dendrimer incoporating nine N2S2-donor
macrocyclic sites. The interaction of these species with selected metal
ions is discussed. A series of cage molecules with varying cavity sizes
has been prepared and their interaction with both (selected) metal ions
and small molecules described. The formation of new large molecular
squares and catenanes involving self-assembly is also presented.
