Organic cage supported metal nanoparticles for applications.

Porous shape-persistent organic cages can anchor metal nanoparticles either inside the cavity or in the external cavity generated through self-assembly. The size of these nanoparticles range from 1-2 nm depending upon the host and can be controlled within a narrow size distribution. The nanoparticles thus formed are quite stable as they are segregated efficiently preventing their association and eventual precipitation. These fine nanoparticles are found to be quite effective in catalyzing a number of organic transformations besides showing interesting emission properties.
