Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Materials Chemistry C: Materials for Optical and Electronic Devices called Novel erbium(III) complexes with 2,6-dimethyl-3,5-heptanedione and different N,N-donor ligands for ormosil and PMMA matrices doping, Author is Martin-Ramos, P.; Lavin, V.; Ramos Silva, M.; Martin, I. R.; Lahoz, F.; Chamorro-Posada, P.; Paixao, J. A.; Martin-Gil, J., which mentions a compound: 18362-64-6, SMILESS is CC(C)C(CC(C(C)C)=O)=O, Molecular C9H16O2, Application In Synthesis of 2,6-Dimethyl-3,5-heptanedione.
Three novel complexes, [Er(dmh)3(bipy)], [Er(dmh)3(bath)] and [Er(dmh)3(5NO2phen)], with 2,6-dimethyl-3,5-heptanedione (Hdmh) as the main sensitizer and either 2,2′-bipyridine (bipy), bathophenanthroline (bath) or 5-nitro-1,10-phenanthroline (5NO2phen) as synergistic ligands were synthesized. Upon excitation at the maximum absorption of the ligands, the complexes show the characteristic near-IR (NIR) luminescence of the Er3+ ions, due to efficient energy transfer from the ligands to the central Er3+ ion via the antenna effect. Single crystals were grown and their structures were determined showing different Er-N distances. The compound with shorter Er-N distances, [Er(dmh)3(5NO2phen)], is the best light harvester and the best for transferring the energy to the lanthanide among the three studied compounds Finally, the novel complexes were assessed for their application in sol-gel and polymer-based waveguides and optical amplifiers through their inclusion into ormosil and polymethylmethacrylate matrixes. The dispersion was successful in the bipy and 5NO2phen cases, with the properties of the hybrid materials mimicking those of the pure complexes.
