Mesocrystals(介晶) are a new class of nanostructured solid materials, which are

most often made of crystallographically (晶向)oriented nanoparticles. Structural

features, properties, and possible applications of mesocrystals are summarized in this

paper. Due to their unique structural features and the resulting physical and

physicochemical properties, mesocrystals are expected to play a significant role in

improving the performance of materials in many applications. These are as diverse as

heterogeneous photocatalysts, electrodes, optoelectronics, biomedical materials,

hard templates, and lightweight structural materials.

In the past 6 years, more and more attention has been paid to mesocrystalline

materials. An increasing number of papers have been published in the literature.

Most of these focused on the characterization of structures and the investigation of

formation mechanisms. The results indicate that the structure and formation

mechanism of a mesocrystal are related to the shape of the nanoparticle, colloidal

stabilization, and vectorial long-range interaction potentials. Surface interaction

between the nanoparticles plays a critical role during the formation process of a

mesocrystal and may be responsible for the formation of external faces. The reason

for the remarkably (almost perfectly in some cases) ordered alignment of

nanoparticles is still poorly understood. Special emphasis has been placed on the

different possible forces that may drive orientation and assembly between

nanoparticles.
