LUMINESCENT DETECTOR OF CATIONS OF ALKALI METALS Russian patent published in 2018 - IPC C09K11/06 C07F3/06 G01N21/64

Abstract RU 2644894 C2

FIELD: chemistry.

SUBSTANCE: material has a composition (H₃O)₂[Zn₄(ur) (Hfdc)₂(fdc)₄]⋅G, where ur - urotropin, fdc^2-=2,5-furandikarboksilat, G=4DMF⋅14H₂O⋅2H₂fdc⋅2ur consists of secondary blocks of the structure {Zn₄(ur)(COO)₁₂}, in which atoms of zinc are coordinated to each atom of urotropine nitrogen, and contains a hydrophobic and hydrophilic cavity. At the same time, in the hydrophilic cavities there are guest hydronium cations capable of substitution for cations of alkali metals.

EFFECT: invention allows to obtain a material that combines the advantages of solid-state fluorescent sensor with a high selectivity and sensitivity towards cations of alkali metals.
