The phrase "aromatic sulfones" is correct and usable in written English.
It can be used in scientific or chemical contexts to refer to a specific class of organic compounds that contain a sulfone group and have an aromatic ring.
Example: "The study focused on the synthesis and properties of various aromatic sulfones, which are known for their stability and reactivity."
Alternatives: "aromatic sulfonyl compounds" or "aromatic sulfone derivatives".
Further DFT also confirmed the feasibility of π π interactions between the benzimidazole rings and the aromatic sulfone compounds.
These membranes were designed to possess all the required properties of proton conductive membrane, namely reasonably swelling, good mechanical, dimensional and oxidative strength, flexibility, low methanol permeability along with reasonable proton conductivity due to bridged aromatic sulfone between functionalized silica.

A novel side-chain-sulfonated aromatic diamine of bis[4- 4-aminophenoxy -2- 3-sulfobenzoyl bis[4- 4-aminophenoxy -2- 3-sulfobenzoyl bis[4- 4-aminophenoxy -2- 3-sulfobenzoyl bis[4- 4-aminophenoxy -2- 3-sulfobenzoyl bis[4- 4-aminophenoxy -2- 3-sulfobenzoyl bis[4- 4-aminophenoxy -2- 3-sulfobenzoyl
The aromatic poly (ether sulfone) composite ion exchange membrane represents a close step towards the design and construction of alternative types of membranes for battery application.
Both in situ and ex situ oxidation stability tests demonstrate that the aromatic poly (ether sulfone) composite ion exchange membrane has excellent stability in vanadium flow battery medium.
Here we describe the preparation and utilization of an aromatic poly (ether sulfone) composite ion exchange membrane for vanadium flow battery application.
The ion exchange groups are constructed by fixing the phosphotungstic acid into the alkaline poly (vinyl pyrrolidone) through the acid-base reaction, while the aromatic poly (ether sulfone) is used as the matrix.
The cathodic cleavage of some aromatic sulfochlorides Ia Ie, sulfonic ethers IIa-IIr, sulfonamides IIIa IIIe and sulfones IVa IVc was studied by way of electrogenerated chemiluminescence in presence of some suitable aromatic hydrocarbons at the dropping mercury electrode or at a platinum disc electrode in a 1 1 acetonitrile/toluene mixture or in DMF.
Controlled molecular weight poly arylene ether sulfone) oligomers with aromatic amine end groups and systematically varied degrees of disulfonation were synthesized by direct polymerization of disulfonated and non-sulfonated 4,4′-dichlorodiphenylsulfone.
