Among these materials, porous organic cages (POCs) have emerged as a promising class, constructed by individually designed macromolecules possessing inherent cavities that are tailor-made, soluble, easily regenerated, and amenable to precise modifications. Analogous to well-established porous framework ...

Porous materials are important in a wide range of applications including molecular separations and catalysis. We demonstrate that covalently bonded organic cages can assemble into crystalline microporous materials. The porosity is prefabricated and intrinsic to the molecular cage structure, as opposed to be...

This is achieved by monitoring how the surface area evolves with respect to time, during a MD simulation. This suggests how the pore channels of various systems, previously thought too small for gas adsorption, are actually suitable candidates for separations. 展开 年份: 2013 ...
The structure of the porous modules can be fine‐tuned for specific applications, such as gas isotope separations, and in some cases the solid﹕tate properties of these materials can be defined by the structure of the porous molecule as viewed in isolation. In this review, the authors focus ...
Gas separation is dependent on the size of these channels and cages relative to the kinetic diameter of the gas. The difference in the kinetic diameter of gas molecules dictates which molecular sieves are useful and provides an indication of selectivity. Microporous zeolite membranes can also be ...
Compared with printed circuit heat exchangers, only small flow separations can be found in G and D structures, which is owing to the smooth surfaces. Large turbulent kinetic energy production, which is favorable for heat transfer, can be observed in G structures. And the heat transfer rate of...
Porous materials are widely used in industry for applications that include chemical separations and gas scrubbing. These materials are typically porous solids, although the liquid state can be easier to manipulate in industrial settings. The idea of comb
Here, we present a chemical approach for desymmetrizing organic cages by dynamic covalent scrambling reactions. This leads to molecules with a distribution of shapes which cannot pack effectively and, hence, do not crystallize, creating porosity in the amorphous solid. The porous properties can be ...
