A Microporous Metal–Organic Framework Incorporating Both Primary and Secondary Building Units for Splitting Alkane Isomers

Abstract

We demonstrate the assembly of a mononuclear metal center, a hexanuclear cluster, and a V-shaped, trapezoidal tetracarboxylate linker into a microporous metal–organic framework featuring an unprecedented 3-nodal (4,4,8)-c lyu topology. The compound, HIAM-302, represents the first example that incorporates both a primary building unit and a hexanuclear secondary building unit in one structure, which should be attributed to the desymmetrized geometry of the organic linker. HIAM-302 possesses optimal pore dimensions and can separate monobranched and dibranched alkanes through selective molecular sieving, which is of significant value in the petrochemical industry.

Infusion of Variable Chemical Structure to Tune Stacking among Metal‐Organic Layers in 2D Nano MOF

“…It is very important to note that structural tunability/adaptability is key feature of MOFs/PCPs. [17][18][19] Apart from such 3D architecture of MOFs, 2D MOFs/PCPs represent one class of materials which are potentially useful in energy storage, optoelectronic property, gas permeation, chemical sensing. [20][21][22][23][24] Structural designability/ tunability remained the most important advantage of such 2D MOFs/PCPs as well.…”

A microporous Zr6@Zr-MOF for the separation of Xe and Kr

“…Self-assembly of common metals and organic linkers into novel crystalline compounds would not only enrich the structural variety of MOFs, but the new materials may also exhibit excellent properties for certain applications. [1][2][3] To this end, the quest for novel MOF structures represents an important component of MOF research.…”
