Covalent Organic Frameworks (COFs), an emerging class of crystalline porous materials, are proposed as a new type of support for grafting lanthanide ions (Ln3+) and employing these hybrid materials as ratiometric luminescent thermometers. A TpBpy-COF-prepared from 1,3,5-triformylphloroglucinol (Tp) and 2,2′-bipyridine-5,5′-diamine (Bpy) grafted with Eu/Tb and Dy acetylacetone (acac) complexes can be successfully used as a luminescent thermometer in the 10-360 K (Eu) and 280-440 K (Tb) ranges with good sensing properties (thermal sensitivity up to 1.403% K-1, temperature uncertainty δT<1 K above 110 K). For the Eu/Tb systems, we observe an unusual and rarely reported behavior, i.e., no thermal quenching of the Tb3+ emission, a result of the absence of ion-to-ligand/host energy back-transfer. The LnCOF materials proposed here could be a new class of materials employed for temperature-sensing applications following up on the well-known luminescent metal-organic framework thermometers.

2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4) is a member of phloroglucinol derivatives. Regarding monomeric phloroglucinols, this group encompasses acryl phloroglucinols, phloroglucinol-terpene adducts, phloroglucinol glycosides, halogenated phloroglucinols, prenylated phloroglucinols, and cyclicroup polyketides.HPLC of Formula: 34374-88-4
