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.
