Supramolecular Materials from Inorganic Building Blocks

Inorganic materials of nanometric dimensions and controllable morphologies are now widely available permitting their use as building blocks in supramolecular structures. Incorporation of inorganic blocks into hybrid structures can yield unique materials that have no naturally occurring or organic synthetic analogues. In this short review, we describe the construction and functions of supramolecular materials prepared using inorganic building blocks, with emphasis on material-like components. Examples described in this review are categorized as (i) inorganic structures within organic assemblies (silica-supported Langmuir monolayers, organic-inorganic lipid bilayer vesicles etc.), (ii) organic components in inorganic nanospaces (mesoporous materials including biocomponents such as peptides and proteins), (iii) organic/inorganic nanohybrid blends (nanorod-liquid crystal blends and surfactant-guided gold nanostructures), and (iv) hierarchic structures (layer-by-layer assemblies of mesoporlous carbons and capsules).
