-
Paragraph 0027; 0036, (2018/03/25)
The invention discloses a aryl sulfonic acid ammonium salt compound, preparation method and application thereof, the main process expressed as follows: formula (I) indicated by the aryl sulfonic acid compound crude product as raw material, in the solvent with the structural formula (II) shown in mixed organic amine, to form the structural formula (III) as shown by a aryl sulfonic acid ammonium salt; the resulting structural formula (III) aryl sulfonic acid ammonium salt shown by the alkali soluble acid or directly to obtain the acid of formula (I) shown in the purification of compounds such as aryl sulfonic acid. The invention is primarily embodied in the [...]: through the low quality aryl sulfonic acid compound refining, effectively reduces the content of harmful impurities, improve the quality of the aryl sulfonic acid compound, reducing the pressure of the downstream use, the process is stable.

A new class of carboxylate and sulfonate esters of 1-hydroxy-2(1H)- quinolone has been demonstrated as nonionic photoacid generators (PAGs). Irradiation of carboxylates and sulfonates of 1-hydroxy-2(1H)-quinolone by UV light (γ≥310 nm) resulted in homolysis of weak N-O bond leading to efficient generation of carboxylic and sulfonic acids, respectively. The mechanism for the homolytic N-O bond cleavage was supported by time-dependent DFT calculations. Photoresponsive 1-(p-styrenesulfonyloxy)-2-quinolone-methyl methacrylate (SSQL-MMA) and 1-(p-styrenesulfonyloxy)-2-quinolone-lauryl acrylate (SSQL-LA) copolymers were synthesized from PAG monomer 1-(p-styrenesulfonyloxy) -2-quinolone, and subsequently controlled surface wettability was demonstrated for the above-mentioned photoresponsive polymers.
