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.

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.

ML2OH were prepared by the method of G. S. Hammond, et al. (1963). Gas chromatog. was carried out on a 5 weight % high-vacuum silicone grease/Chromasorb W column, with He carrier gas and a thermal conductivity detector. The chelates were characterized also by elemental anal., ir spectroscopy, and thermogravimetric anal. (TGA). Good gas chromatograms were obtained for ML2 and ML3, except for CoL3, which was partially decomposed TGA curves of ML2 and ML3 gave the decreasing order of volatility as Be > Fe > Cu > Co(II) > Co(III) > Cr(III) > Al > Ni, which corresponded with the order of retention times, except that Fe and Al were interchanged. ML2OH were not eluted at 200-70°, except when M = Lu and Er, in which case the chelates were eluted at column temperatures of 200-50°. Apparently, HL is generally unsuitable for the gas chromatog. of rare earth metals.

The spectral results indicated the existence of two Eu sites in the dipy compound but only one in the o-phen complex. The x-ray results show that the o-phen complex has a single geometry, the coordination polyhedron of which is best approximated as a square antiprism, whereas there are two geometries in the dipy complex, both of which are also square antiprisms but are more distorted. In all cases the chelate rings span the s edges of the square antiprism and the bond distances are typical for this type of complex.
