General Description

2-Fluoroterephthalic acid is a chemical compound with the formula C8H5FO4. It is a derivative of terephthalic acid, in which one of the hydrogen atoms on the aromatic ring is replaced by a fluorine atom. This substitution results in a compound that is widely used in the production of polymers, such as polyethylene terephthalate (PET), which is commonly used in the manufacture of plastic bottles and containers. 2-Fluoroterephthalic acid has also been studied for its potential use in organic electronics and as a precursor for the synthesis of various pharmaceuticals and agrochemicals. It is considered to be relatively stable and non-toxic, making it a valuable building block for a range of industrial and research applications.

Cerium-based metal organic frameworks with UiO-66 architecture: Synthesis, properties and redox catalytic activity

A series of nine Ce(IV)-based metal organic frameworks with the UiO-66 structure containing linker molecules of different sizes and functionalities were obtained under mild synthesis conditions and short reaction times. Thermal and chemical stabilities were determined and a Ce-UiO-66-BDC/TEMPO system was successfully employed for the aerobic oxidation of benzyl alcohol.
