Magnetic and optical studies of a new family of multidimensional and multiproperty PO-lanthanide(iii) derived systems

Abstract

A new family of lanthanide compounds has been synthesized using 1,2-bis(diphenylphosphino)ethane dioxide (DppeO2) as a O-coordinated ligand through the phosphoryl group to the lanthanide(III) cations and structurally, magnetically and optically...

Interesting chemical and physical features of the products of the reactions between trivalent lanthanoids and a tetradentate Schiff base derived from cyclohexane-1,2-diamine

“…The susceptibility data were fitted assuming implicitly a regular distribution of the m j states. The Hamiltonian used is represented by eqn (1), where Ŝ is the spin operator, L is the orbit operator, 45,46 λ is the spin-orbit coupling and Δ describes the energy gap between m L components. The value for the orbital reduction parameter k was assumed as 1 (the Ln III ions behave as purely ionic).…”

Three derivatives of phenacyldiphenylphosphine oxide: influence of aromatic and alkyl substituents on the luminescence sensitization of four Ln(NO3)3 salts

“…2 The ability of the phosphine oxide group to facilitate this sensitization process has also been investigated, but to a lesser extent. [15][16][17][18][19][20][21][22] Our goal with this work was to tease out the role of each functional group of the ligandthe carbonyl vs. the phosphine oxidein both the Ln(III) binding and luminescence properties of its resultant complexes. To investigate this, we prepared the three derivatives 2-4 shown in Fig.…”
