Application of 14098-44-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 14098-44-3, Name is Benzo-15-crown-5, molecular formula is C14H20O5. In a Article，once mentioned of 14098-44-3
A series of tautomeric chromoionophores were prepared photochemically from 1-aryloxyanthraquinones and 4?-aminobenzo-15-crown-5 ether. All the synthesized dyes can bind strontium and barium cations as sandwich-type 2:1 ligand?metal complexes that show higher stability constants (K2:1) than the corresponding 1:1 complexes (K1:1), the K2:1/K1:1ratio reaching a value of 10 (in MeCN). The inverse relation, i.e. K2:1 < K1:1, is observed for the related complexes of unsubstituted benzo-15-crown-5 ether. The sandwich complexes were studied by spectrophotometry,1H NMR spectroscopy, mass spectrometry, and density functional theory calculations. A correlation was found between the K2:1/K1:1ratio and the number of short stacking contacts in the sandwich complex. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
