Colloidal suspensions of highly luminescent lanthanide-based coordination polymer molecular alloys for ink-jet printing and tagging of technical liquids

Abstract

Highly luminescent and color-tunable stable colloidal suspensions of molecular alloys are reported. They are produced via a green synthetic route in ethanol medium. The mean hydrodynamic diameter of the colloids...

Investigation of Intermetallic Energy Transfers in Lanthanide Coordination Polymers Molecular Alloys: Case Study of Trimesate-Based Compounds

“…For more than two decades, lanthanide-based coordination polymers have attracted a growing interest. Indeed, because of the unique magnetic and optical properties of the lanthanide ions, − they can find their application in several technological fields , such as thermometry, − chemical sensing, , molecular magnetism, − light and display, − or material tagging. − Because of the shielded character of their valence orbitals, lanthanide ion chemical bonds present a very weak covalent component and lanthanide ions behave as hard Pearson’s acids. , Therefore, because they present almost no structuring effect and great chemical affinity for ligands with donor oxygen atoms, lanthanide ions have been widely used in association with benzene-poly-carboxylate ligands. , Indeed, these ligands present a great structuring effect, via π-stacking and hydrogen bonds, which favors the formation of crystallized coordination polymers. Moreover, these ligands, which exhibit an extended conjugated π-system, can provide an efficient antenna effect, which is beneficial as far as luminescent properties are targeted .…”

Hexanuclear Molecular Precursors as Tools to Design Luminescent Coordination Polymers with Lanthanide Segregation

“…Lanthanide-based coordination polymers attract great interest. − Indeed, because of the unique optical , and magnetic properties of the lanthanide ions, they present great interest in various technological fields such as molecular thermometry, − chemical sensing, − light and display, , or the fight against counterfeiting, − for instance. Therefore, the quest for highly luminescent lanthanide-based coordination polymers is a continuous concern. ,− Because lanthanide ions present no structuring effect, most of the reported studies focus their attention on the choice of the ligand. ,,− This synthetic strategy offered very luminescent coordination polymers with high quantum yields. − Some recent works suggest that an extended inorganic sublattice surrounded by ligands that act both as antennas and as spacers is relevant as far as highly luminescent coordination polymers are targeted. − …”

Synthesis, Crystal Structure, and Luminescence Properties of the Iso-Reticular Series of Lanthanide Coordination Polymers Synthesized from Hexa-Lanthanide Molecular Precursors

“…Lanthanide-based coordination compounds, complexes or coordination polymers, have been widely studied in the last two decades. Indeed, because of the unique physical and chemical properties of the lanthanide ions, , these compounds exhibit interesting magnetic − and optical properties , that make them promising candidates in various technological fields such as molecular thermometry, , chemical sensing, − light and displays, , or fight against counterfeiting, − for instance. All these potential applications require highly emissive materials, and therefore, the quest for new lanthanide-based coordination compounds exhibiting bright luminescence constitutes a continuous concern. − …”
