Y8O(OH)15(CO3)3Cl: an excellent short-wave UV nonlinear optical material exhibiting an infrequent three-dimensional inorganic cationic framework

An excellent short-wave UV nonlinear optical material, Y8O(OH)15(CO3)3Cl, featured an infrequent three-dimensional inorganic cationic framework.

Highly efficient Cr2O72−removal of a 3D metal-organic framework fabricated by tandem single-crystal to single-crystal transformations from a 1D coordination array

Tandem single-crystal to single-crystal (SC–SC) transformation of a 1D neutral chain affords a 3D cationic framework, showing highly efficient Cr2O72−captureviaSC–SC anion-exchange.

Novel photo- and/or thermochromic MOFs derived from bipyridinium carboxylate ligands

Two new Zn-MOFs based on 1-(3,5-dicarboxyphenyl)-4,4′-bipyridinium bromide have been synthesized. Compound 1 has a 3D interpenetrated cationic framework with photo- and thermochromism, while compound 2 possesses a 2D layered cationic network with only photochromism.

An arsenicniobate-based 3D framework with selective adsorption and anion-exchange properties

An arsenicniobate-based cationic framework shows a high adsorption selectivity of water and ethanol and effectively removes toxic SCN− anions.

Diverse isostructural MOFs by postsynthetic metal node metathesis: anionic-to-cationic framework conversion, luminescence and separation of dyes

Postsynthetic metal-node metathesis of a flexible, yet robust porous anionic Cd–MOF with different metal ions of varying ionic radii, charges and chemical nature leads to diverse isostructural MOFs. The Eu@MOF and Tb@MOF – accessed by PSME – are brilliantly luminescent. The modified MOFs permit organic dye separation.
