Supramolecular Self-Assembly of Hybrid Colloidal Systems

摘要

Hybrid materials compose a new class of nanostructured free- or bound-disperse systems that combine organic and inorganic components in their composition. The properties of the hybrid materials are governed by the known colloid-chemical regularities. The phenomenon of the synergism in the properties of such materials is realized due to the interaction between system components at interfaces and depends on the structural order of the systems. In the last decade, a new field of researches has appeared, i.e., supramolecular self-assembly, which implies the simultaneous or successive integration of components into a unified structure via the formation of numerous noncovalent (hydrogen, ionic, coordination, etc.) bonds. This review lets readers get acquainted with different types of supramolecular self-assembly of hybrid nanosystems at interfaces. The methods of forming hybrid systems are discussed by the examples of mixtures of classical cationic surfactants and functionalized zinc porphyrinates used as organic linkers in combination with spherical metal nanoparticles and planar inorganic matrices (graphene oxide and layered hydroxides of rare-earth metals). The relation between the structure and properties of hybrid materials are considered in detail, and the possible practical applications and the perspectives of the development of this field of colloid chemistry for the nearest decade are discussed.
