In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 52093-25-1, name is Europium(III) trifluoromethanesulfonate, introducing its new discovery. name: Europium(III) trifluoromethanesulfonate
Four New Families of Polynuclear Zn-Ln Coordination Clusters. Synthetic, Topological, Magnetic, and Luminescent Aspects
The employment of three structurally related Schiff bases H2L1, H2L2, and H3L3 with zinc and lanthanide salts under various reaction conditions, gave four families of compounds formulated as [ZnII2LnIII2(L1)4(EtOH)6][ClO4]2 (1-3), [ZnII5Ln(OH)(L1)6(H2O)] (4-6), [ZnII4LnIII2(OH)2(L2)4 (OAc)2(NO3)2(DMF)3]¡¤DMF (7-9), and [ZnII2LnIII2(L3)2(NO3)2(CO3)2(CH3OH)2] (10-12) with robust and novel topologies. Synthetic aspects are discussed. A comprehensive topological analysis of all reported ZnII/LnIII CCs with a core nuclearity of four and above is presented and identifies that families (4-6) and (7-9) are the first examples of the 2,3,4M6-1 motif in ZnII/LnIII chemistry. Magnetic studies are presented for the DyIII analogues (1, 7, and 10) are presented, 7 demonstrates field-induced slow relaxation of the magnetization. Fluorescence studies are also discussed.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 52093-25-1 is helpful to your research. name: Europium(III) trifluoromethanesulfonate
