The Designed Self-Assembly of Multicomponent and Multicompartmental Cylindrical Nanoarchitectures

摘要

The polytopc linear 4 and circular 5 ligands undergo self-assembly with copper(I) and silver(I)ions to generate the large iorganic entities 2 and 3 containing, two and three internal cavities, respectively. The process amounts to the spontaneous assembly of a total of 15 and 19 particles to yield multicompartmental architectures. The crystal structures of two such complexes have been determined. They confirm the nature of the entities formed and show that in addition several substrate species (anions and solvent molecules)are contained in the cavities. The generation of architectures 2 and 3 presents several important features:it reparesents a multicomponent mixed-ligand self-assembly process involving self-compartmentalisation with siultaneous inclusion (and selection)of multiple substrate species. Such features are of interest for both the analogies with bioloigical processes and the potential applications in nanoscience. They also amount to a further step in the design of systems of increasing structural and functional complexity.
