The influence of imidazolium counterions on the luminescence properties of Cnmim[Eu(tta)4] tetrakis complexes in solid-state and ionic liquid solutions

Terbium based (poly)ionic liquids for anti-counterfeiting and droplet manipulation

“…37 Therefore, the introduction of rare earth ions enhances the magnetic susceptibility of M(P)ILs. 38 Meanwhile, lanthanide M(P)ILs show significant advantages in luminescent applications due to their high color purity, 39 high color intensity, 40 and long lifespan 41 of fluorescence. In our group, 42 we synthesized a perylene diimide (PDI)-based Gd-containing magnetic ionic liquid Per-6-Diimi[Gd(NO 3 ) 4 ].…”

The influence of different cations on the structure and spectral properties of Ln3+ tetrakis-complexes with the CAPh-type ligand dimethyl-N-trichloroacetylamidophosphate

“…In several studies devoted to Ln 3+ tetrakis-β-diketonates it was shown that the nature of cations in these compounds can influence the lifetime and quantum efficiency of the Ln 3+ emission. 25–30 This may be related to the probability of non-radiative deactivation of the compound's excited state which depends, among other things, on the rigidness of the structure of the complex. The point symmetry around the Ln 3+ can be disturbed by the interaction between the lateral groups of the ligands and the counterion.…”
