Spectroscopic Studies of Neodymium and Europium Phosphoro-azo β-Diketonates

Abstract

New conplexes of lanthanides (Nd, Eu) with phosphoro-azo derivatives of β-diketones were synthesized. Optical properties of these compounds were investigated and confronted with the structure and single crystal spectra of different types of earlier reported lanthanide phosphoro-azo β-diketonates. The exchange of the N-P-O-Me ligand group by the Ν-P-ΝR2 one plays only a minor role in binding character of lanthanide ions but strongly affects biological functions and properties of lanthanide systems. In vitro experiment ohs cytotoxicity of the samples was performed using 10T 1 /2, L1, MCF, DETA and Μeω-132 cell lines.

Syntheses, spectroscopic study and crystal structures of some new N-benzoylphosphoric triamides

“…In recent years, investigations on N-benzoylphosphoric triamides are an important part of phosphoramidate chemistry due to their synthetic and structural [1][2][3], coordination [4][5][6][7][8] and biological [9] applications. These molecules have -C(O)NHP(O)-skeleton and the existence of peptide group in these derivatives cause them biologically active anticancer drugs [10].…”

Spectroscopy and structure of [LnL3bipy] and [LnL3phen] complexes with CAPh type ligand dimethylbenzoylamidophosphate

“…Oscillator strength values P( Â 10 8 ) of hypersensitive 4 I 9/2 -4 G 5/2 , 2 G 7/2 transition for Nd1, Nd2 and related Nd III complexes [11,12]. and at 345 nm (for Eu2).…”

Structure and spectroscopy of NaNd(SP)4 chelate: a new type of lanthanide luminophore

“…GðG2Þ and GðR7Þ are Casimir operators for the Lie groups G 2 and R 7 , respectively. The three-particle configuration interaction is expressed by 3,4,6,7,8), where T i are parameters andt i are three-particle operators. The electrostatically correlated spin-orbit perturbation is represented by the P k parameters and those of the spin-spin and spin-other-orbit relativistic corrections by the M J parameters.…”
