Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, Formula: C10H20O5.
LUMINESCENCE OF DIVALENT EUROPIUM COMPLEXES WITH CROWN ETHERS, CRYPTANDS AND POLYETHYLENE GLYCOLS.
The luminescence properties of the divalent europium complexes with crown ethers, cryptands and polyethylene glycols were studied. The observed intensity of luminescence is generally reported. The most intense luminescence is produced by a methanolic solution of the 15-crown-5 complex with europium(II), the intensity of which is 600 times greater than that of a solution of EuCl//2 in methanol with the same europium(II) concentration. The enhancement of the emission intensity as a result of the formation of complexes with crown ethers can be attributed to ‘insulation’ of the europium(II) ion from close approach of the solvent molecules which would produce radiationless energy losses.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Formula: C10H20O5. In my other articles, you can also check out more blogs about 33100-27-5
