Description
Summary:Near-Infrared-emissive materials have attracted substantial attention due to their unique properties. To solve the urgent requirements of high-water stability materials can be widely used in practical engineering. Hence, a novel near infrared luminescent and highly water-stable lanthanide-organic frameworks (namely Yb-MOF-Y) was synthesized under hydrothermal method by anchoring functionalized, rigid ligands 2,3,5,6-tetrafluoroterephthalic acid and 1,10-phenanthroline onto its skeleton. It is notable that the Yb-MOF-Y possess high structural stability in water for 28 days, in different acid-base solutions (pH = 4-10) for 3 days and the thermal stability in water (-20 °C to 60 °C) for 3 days. Remarkably, luminescent studies reveal that the Yb-MOF-Y can be used as a potential material in near infrared field.
