Krasheninnikov, A. A. published an article about the compound: quinoliniumhydrogensulphate( cas:530-66-5,SMILESS:[O-]S(=O)(O)=O.C12=CC=C[NH+]=C1C=CC=C2 ).Computed Properties of C9H9NO4S. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:530-66-5) through the article.
Luminescence quenching constants for systems containing acid salts of heterocyclic bases (pyridine, quinoline, acridine) and aromatic hydrocarbons (phenanthrene, anthracene, naphthacene) indicated that charge-transfer complex formation occurred and that quenching resulted from electron transfer from the aromatic hydrocarbon to the heterocyclic cation.
