Photophysical Properties of Rare Earth Diclofenac Complexes in the Solid State

Abstract: We elaborate on the use of the comparably complex, but widely used and readily accessible pharmaceutical diclofenac, the molecular structure of which contains aromatic units with chloro-, amine-, and carboxylate substituents, all of which were deemed to be useful in the formation of efficiently luminescing rare earth complexes. However, efficient luminophores with quantum yields of 48 % in the case of Tb 3þ could only be obtained by the additional employment of chelating N-donors (1,10-phenanthroline and 2,2 0… Show more

“…As one can see, the Δν values for the complexes are slightly lower but close to the sodium salt, indicating that the fluf ligand coordinates to Ln 3+ ions through a bidentate chelate coordination mode . These results are corroborated with the FTIR data reported in previous reports. ,, The coordination of ancillary ligands to the Ln 3+ ion was confirmed by the shift of the heteroaromatic C–N mode and the phosphine oxides (ν PO ) and sulfoxide (ν SO ) stretching modes to lower energies when compared with the free organic molecules, as can be seen in Table S2.…”

“…[17] Furthermore, Peter Junk, Ulrich Kynast, and co-workers discuss the important solid-state luminescence of rare earth diclofenac complexes. [18] Photovoltaic cells convert light energy into electrical energy and discovery of new materials for the production of efficient solar cells is important to break free from the dependency on non-renewable energy sources. Rapid advances in polymer solar cell efficiency have been made in recent years through the fundamental understanding of the structure-property relationships of light-absorbing polymers.…”
