Development of Coordination Nanomaterials Situated in Dimensional Crossover Region

Abstract

Coordination nanomaterials, which are made from a bottom-up assembly of metal ions and organic ligands, have been of particular interest to researchers because of their high degrees of structural designability and tunability based on substitutions of their structural components. In this review, successful fabrications and electronic and physical properties of mixed-valence multi-legged ladder complexes and crystalline oriented metal–organic framework (MOF) thin films, which straddle among one-, two-, and three-dimensional systems are described. Their unique electronic properties depending on the number of constituent legs and downsizing effects on physical properties have recently been overviewed.
