“…Pentafluorobenzoic acid (Hcarb 14 ) demonstrates p K a of 1.6–1.8 . This results in the extreme lability of the complexes with fluorobenzoate‐anions: their composition depends not only on the lanthanide ion and the synthesis conditions, but also on the crystallization conditions , , , , , …”

“…Decrease of the number of the fluorine substituents (carb = carb 15 ‐carb 22 ) results in less variability of the single crystal structures , . Analysis of the complexes with the fluorobenzoate anions (Figure ) revealed that most of the studied complexes can be divided into two groups by the type of coordination environment of the lanthanide ion in a crystal (Figure ): with two ortho ‐substituents (n ortho ) in the ligand (Figure a) and with one n ortho (Figure b).…”

“…Among those, lanthanide benzoates play an important role due to their high stability, excellent luminescence properties and ease of chemical modification . Nowadays undirected synthesis and search for new material precursors is more and more substituted by the directed chemical design, allowing to obtain the probes with the specific properties demanded by the particular application . At the same time, lanthanide benzoates are known for their high lability, resulted from high acidity of benzoic acids.…”

Lanthanide tetrafluoroterephthalates, Ln 2 ftp 3 ·6H 2 O (Ln = Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Tm, Yb), (Eu x Tb 1-x ) 2 ftp 3 ·6H 2 O, and (Eu x Tb 1-x ) 2 ftp 3 (Phen) 2 ·2H 2 O (Phen = o-phenanthroline) were obtained for the first time and studied in detail. Water IntroductionOne of the prospective applications of luminescent materials is security printing, in which ink-jet printing plays an important role. A variety of luminescent materials have been considered for this application; however, most of them suffered from certain problems that hampered their practical use; for example, quantum-dot-based inks [1] are toxic, organic dyes [2] have small Stokes shifts, and inorganic lanthanide-based inks [3] have low brightness.Lanthanide coordination compounds (Ln CCs) possess features that predetermine their high potential as security printing dyes, namely, high brightness of luminescence, high thermal and UV stability, low toxicity, and a large Stokes shift. [4,5] As there is a large energy difference between the absorbing state of the ligand and the emitting state of the lanthanide, these materials typically absorb UV radiation and emit in the Vis/IR range. [6,7] Thus, they are colorless if observed with the naked eye but exhibit intense luminescence if irradiated with UV light, which is very important for this application.Water is one of the most suitable solvents for ink-jet printing, because it is an environmentally friendly solvent, possesses suitable viscosity, and does not induce the corrosion of printer parts; thus, water-soluble luminescent inks are highly sought.[a]
