Computational characterization and prediction of metal-organic framework properties [PDF]

open access: yes, 2015
In this introductory review, we give an overview of the computational chemistry methods commonly used in the field of metal-organic frameworks (MOFs), to describe or predict the structures themselves and characterize their various properties, either at ...

Tuning excited state electronic structure and charge transport in covalent organic frameworks for enhanced photocatalytic performance

open access: yesNature Communications, 2023
Covalent organic frameworks (COFs) represent an emerging class of organic photocatalysts. However, their complicated structures lead to indeterminacy about photocatalytic active sites and reaction mechanisms.

[1,3]/[1,4]-Sulfur atom migration in β-hydroxyalkylphosphine sulfides

open access: yesBeilstein Journal of Organic Chemistry, 2020
β-Hydroxyalkylphosphine sulfides undergo [1,3]- or [1,4]-sulfur atom phosphorus-to-carbon migration in the presence of Lewis or Brønsted acids. The direction of sulfur atom migration depends on the type of acid used for the reaction. In the presence of a

Behaviours of natural organic matter in membrane filtration for surface water treatment : a review [PDF]

open access: yes, 2006
Membrane application in surface water treatment provides many advantages over conventional treatment. However, this effort is hampered by the fouling issue, which restricts its widespread application due to increases in hydraulic resistances, operational

Diverse Biological Activity of Benzofuroxan/Sterically Hindered Phenols Hybrids

open access: yesPharmaceuticals, 2023
Combining two pharmacophores in a molecule can lead to useful synergistic effects. Herein, we show hybrid systems that combine sterically hindered phenols with dinitrobenzofuroxan fragments exhibit a broad range of biological activities.

A Perspective on the Synthesis, Purification, and Characterization of Porous Organic Cages [PDF]

open access: yes, 2016
[Image: see text] Porous organic cages present many opportunities in functional materials chemistry, but the synthetic challenges for these molecular solids are somewhat different from those faced in the areas of metal–organic frameworks, covalent ...

Methods for the synthesis of polyhydroxylated piperidines by diastereoselective dihydroxylation: Exploitation in the two-directional synthesis of aza-C-linked disaccharide derivatives [PDF]

open access: yes, 2005
Background: Many polyhydroxylated piperidines are inhibitors of the oligosaccharide processing enzymes, glycosidases and glycosyltransferases. Aza-C-linked disaccharide mimetics are compounds in which saturated polyhydroxylated nitrogen and oxygen ...
