Molecular engineering route to two dimensional heterostructural nanohybrid materials

Heterostructural nanohybrid materials are the group of nanohybrids^1–3 in which two distinct structural components are integrated into one chemical compound. In general, two-dimensional nanohybrids are those that contain the layered structure as one of their structural components. Diverse structural types can be combined into a layer structure to give rise to the interesting two-dimensional heterostructural nanohybrids such as layer-layer, particle-layer, and moleculelayer materials.^2,4,5 Because each component is regularly arranged and chemically interacts with each other in nanoscale and even in molecular scale, their nanohybrids exhibit the fascinating physical and chemical properties distinguished from each component and their physical mixture. It is widely recognized that hybridization leads to remarkable synergic effects such as enhancement of various stabilities, improvement of textural properties, increase in process ability, accomplishment of quantum size and/or confinement phenomena, etc.
