Molecular Self-Assembly with Modularization and Directionality: Vector- Manipulation at Metal Centers

Abstract

The account highlights an important approach to supramolecular self-assembly via “vector-manipulation at metal centers” ranging from Werner-system to Cotton-system coordination compounds. The approach has been successfully employed in the architecture of container molecules like metal analogues of the bowl-shaped calixarenes and metal-linked calixarene-based carcerands and carceplexes. The concepts of metal vector and vector-manipulation at metal centers were further interpreted based upon the stereochemistry and trans- or cis-effect of ligands in the substitution reactions at metal centers. Keywords: self-assembly reaction, supramolecular chemistry, molecular array, nanotechnology, ligands, platinum(II) center, werner-type metal vector
