Composed from discete units, porous molecular materials (PMMs) possess unique properties not observed for conventional, extended, solids, such as solution processibility and permanent porosity in the liquid phase. However, identifying the origin of porosity is not a trivial process, especially for amorphous or liquid phases. Furthermore, the assembly of molecular components is typically governed by a subtle balance of weak intermolecular forces that makes structure prediction challenging. Accordingly, in this review we canvass the crucial role of molecular simulations in the characterisation and design of PMMs. We will outline strategies for modelling porosity in crystalline, amorphous and liquid phases and also describe the state-of-the-art methods used for high-throughput screening of large datasets to identify materials that exhibit novel performance characteristics.

“…85 P/P 0 , which directly indicates that the nanoarchitecture of the HS nanospheres in particular the hollow framework with the microporous shells, are perfectly preserved in the HS-film without any collapse ( Figure 2). 30 This important finding means that the unique nanostructural properties of the HS can be exploited for the fabrication of solid-like electrolytes that is, employing the empty hollow space for liquid loading and the microporous silica shells for liquids confining. It should be pointed out that in principle the abundant micropores across the silica shells should work with a similar function of capillary action to keep the liquids from leaking and evaporating, making the full liquid-soaked HS-powder and HS-film still in apparent dry solid-state.…”

The growth and proliferation of lithium (Li) dendrites during cell recharge are currently unavoidable, which seriously hinders the development and application of rechargeable Li metal batteries. Solid electrolytes with robust mechanical modulus are regarded as a promising approach to overcome the dendrite problems. However, their room-temperature ionic conductivities are usually too low to reach the level required for normal battery operation. Here, a class of novel solid electrolytes with liquid-like room-temperature ionic conductivities (>1 mS cm(-1)) has been successfully synthesized by taking advantage of the unique nanoarchitectures of hollow silica (HS) spheres to confine liquid electrolytes in hollow space to afford high conductivities (2.5 mS cm(-1)). In a symmetric lithium/lithium cell, the solid-like electrolytes demonstrate a robust performance against the Li dendrite problem, preventing the cell from short circuiting at current densities ranging from 0.16 to 0.32 mA cm(-2) over an extended period of time. Moreover, the high flexibility and compatibility of HS nanoarchitectures, in principle, enables broad tunability to choose desired liquids for the fabrication of other kinds of solid-like electrolytes, such as those containing Na(+), Mg(2+), or Al(3+) as conductive media, providing a useful alternative strategy for the development of next generation rechargeable batteries.

“…This porous liquid can work as a promising candidate for gas separation, by taking advantage of its liquidlike polymeric matrices as a separation medium and the empty cavities as gas transport pathway. 174 As mentioned above, the dispersibility of functionalized MSNs has not always been evaluated in an appropriate manner. Careful evaluation of the dispersibility of MSNs should be applied for future applications.…”

IMMA. His current research interests include mesostructured materials, and several fields of inorganic materials chemistry. Some examples are intercalation chemistry, silicate chemistry, inorganic polymers, sol-gel chemistry, inorganic-organic hybrids, and self-organized materials. AbstractMesoporous silica nanoparticles (MSNs) with colloidal stability have attracted increasing interest because of their important properties, such as high transparency and cell uptake. Colloidal MSNs are comprehensively reviewed from the viewpoints of their preparation, characterization, and applications which include biomedical, catalytic, and optical materials. The following two points have been emphasized. The first point is that this review covers the widest range of introduction and discussion of the preparation and applications of both colloidal and noncolloidal MSNs. The second point is that this account contains a discussion from the viewpoints of both inorganic and colloid chemistries. After the introduction of the historical background of preparation of MSNs, preparative methods of colloidal MSNs and the major factors for the preparation of nanosized and colloidal MSNs are discussed. The methods to control the size, composition, morphology, and pore size of MSNs are also presented. Appropriate methods to obtain MSNs with high colloidal dispersibility are also discussed. Applications of colloidal MSNs are introduced with an emphasis on the colloidal stability. Issues to be addressed for further developments of colloidal MSNs are finally described.
