He(I) photoelectron spectra of lanthanum tris-yS -diketonate complexes have been studied and the spectra interpreted on the basis of quantum chemical calculations of ground and ionized states by X -DV and ab initio methods [54]. The comparative analysis of the photoelectron spectra of Sc, and Lu tris-acetylacetonates showed that substitution of one oxygen atom by NH group shifts the two pairs of n and n orbitals to a different extent. The IE (ionization energy) values for (e) and 7T3 (ai) orbitals decreased by 0.8-1.0 eV. The n and n+ molecular orbital two pair bands showed a weak shift of 0.1 eV or less.

The impetus for low temperature aldol processes in the absence or minimization of organic solvent has resulted in several new approaches. For example, Dewa et al. describe an aldehyde-ketone condensation catalyst that can be suspended in water, prepared by reacting lanthanum tris(isopropoxide) with anthracenebisresorcinol (ABR). A polymeric aquo complex with several 1,2-linked ABRs and two (LaOH) + groups is formed, coordinating 30 water molecules and relatively stable to decomposition. The base strength of this complex approached that of aqueous NaaCOs. 

PZT and PLZT. The development of polycrystalline lead lanthanum zir-conate-titanate (PLZT) electronic ceramic monoliths, which fully transmit incident light, requires methods for controlling stoichiometry, impurity content, porosity, grain size, and so on. Alkoxy-derived PLZT powders were prepared by hydrolytic decomposition of mixed-metal alkoxides [40]. The Zr and Ti alkoxides were synthesized by the ammonia method, and the lanthanum tris-isopropoxide was synthesized by the metal/alcohol reaction method, which were described in the previous section. The Pb alkoxide was prepared by the reaction of anhydrous lead acetate, Pb(C2H302)2, with sodium isoamyloxide, NaOCsHn [40] ...

In 2011, Rowan and Weder et al. described the self-healing properties of a linear metallopolymer. fii order to obtain self-healing behavior, the authors used UV light [44], For this purpose, poly (ethylene-co-butylene) was functionalized with two 2,6-fi/s(l -methylbenzimidazolyl)pyridine moieties at the termini and the subsequent addition of zinc di[Z>/s(trifluoromethylsulfonyl)imide] or lanthanum tri[6/s(trifluoromethylsulfonyl)imide] led to a linear metallopolymer.
