“…The formation of Ln 3+ /beta-ketoester complexes involving low molecular weight organic compounds is well documented. [24][25][26] To the best of our knowledge, however, there are no precedents of single-chain polymer nanoparticle formation via intrachain lanthanide/beta-ketoester complex formation. Successful preparation of Eu-SCNPs was confirmed by a combination of structural and size characterization techniques.…”

The maximum permissible concentration (m.p.c.) of Cu2+ ions in drinking water, as set by the World Health Organization (WHO) is m.p.c. (Cu2+)WHO = 30 μM, whereas the US Environmental Protection Agency (EPA) establishes a more restrictive value of m.p.c. (Cu2+)EPA = 20 μM. Herein, we develop−for the first time ever−a family of m.p.c. (Cu2+) “visual” pass/fail sensors based on water‐soluble lanthanide‐containing single‐chain nanoparticles (SCNPs) exhibiting an average hydrodynamic diameter less than 10 nm. Both europium (Eu)‐ and terbium (Tb)‐based SCNPs allow excessive Cu2+ to be readily detected in water, as indicated by the red‐to‐transparent and green‐to‐transparent changes, respectively, under ultra‐violet (UV) light irradiation, occurring at 30 μM Cu2+ in both cases. Complementary, dysprosium (Dy)‐based SCNPs show a yellow color‐to‐transparent transition under UV light irradiation at approximately 15 μM Cu2+. Eu‐, Tb‐ and Dy‐containing SCNPs prove to be selective for Cu2+ ions as they do not respond against other metal ions, such as Fe2+, Ag+, Co2+, Ba2+, Ni2+, Hg2+, Pb2+, Zn2+, Fe3+, Ca2+, Mn2+, Mg2+ or Cr3+. These new m.p.c. (Cu2+) “visual” pass/fail sensors are thoroughly characterized by a combination of techniques, including size exclusion chromatography, dynamic light scattering, inductively coupled plasma‐mass spectrometry, as well as infrared, UV and fluorescence spectroscopy.This article is protected by copyright.

“…In addition, the PM7 method calculates hydrogen bonds in more detail, which makes it possible to better describe non-covalent interactions. The use of PM7 in combination with the SPARKLE model, in which the lanthanide atom is represented as a point charge [41][42], makes it possible to obtain reliable data on the geometry of lanthanide complexes with both aliphatic and aromatic ligands.…”

New complexes of Dy (III) and Gd (III) with b-diketones containing unsaturated and aryl substituents were synthesized. Metal polymers based on synthesized complexes were obtained by the method of radical polymerization. The composition and structure of synthesized complexes and metal polymers are established. It is shown that during polymerization the coordination environment of the central ion remains unchanged. The spectral-luminescent characteristics of the synthesized compounds were studied. The presence of water molecules in the immediate coordination environment causes a low intensity of emission of monomeric dysprosium complexes. In the luminescence spectra of metal polymers, there are bands magnetic dipole transition (4F9 → 6H15/2) and electric dipole transition (4F9 → 6H13/2). The close energies of the triplet level of the ligand and the resonant level of the dysprosium ion cause low emission characteristics of the synthesized dysprosium complexes.

In this chapter, we will discuss diverse aspects of the energetics of metal β‐diketonates and their derivatives. By “energetics” we mean thermochemical and related studies, and so we include enthalpies of reaction and of formation as well as equilibrium measurements and stability constants. We will also discuss the gain or loss of an electron, and therefore consider ionization potentials, electron affinities, and electrochemical potentials. By metal β‐diketonates and derivatives we mean, most generally, species with a substructure of the type [M(dik) n ], where dik (β‐diketonato) is an organic monovalent anion of structure (RC(X)C(R 1 )C(O)R 2 ) − and M is an arbitrary metal. For completeness and additional insights, in this chapter we will also consider M to be virtually all elements (nonmetal, metalloid, or metal), and eventually we will include hydrogen.
