So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Martin-Ramos, P.; Lavin, V.; Ramos Silva, M.; Martin, I. R.; Lahoz, F.; Chamorro-Posada, P.; Paixao, J. A.; Martin-Gil, J. researched the compound: 2,6-Dimethyl-3,5-heptanedione( cas:18362-64-6 ).Computed Properties of C9H16O2.They published the article 《Novel erbium(III) complexes with 2,6-dimethyl-3,5-heptanedione and different N,N-donor ligands for ormosil and PMMA matrices doping》 about this compound( cas:18362-64-6 ) in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices. Keywords: erbium methylheptanedione bipy phen preparation IR luminescence quenching lifetime; ormosil PMMA dispersed erbium methylheptanedione bipy phen waveguide amplifier; crystal structure erbium methylheptanedione bipy phen. We’ll tell you more about this compound (cas:18362-64-6).
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.
From this literature《Novel erbium(III) complexes with 2,6-dimethyl-3,5-heptanedione and different N,N-donor ligands for ormosil and PMMA matrices doping》,we know some information about this compound(18362-64-6)Computed Properties of C9H16O2, but this is not all information, there are many literatures related to this compound(18362-64-6).
