Efficient Multi-stimulus-Responsive Luminescent Eu(III)-Modified HOFs Materials: Detecting Thiram and Caffeic Acid and Constructing a Flexible Substrate Anti-counterfeiting Platform

“…According to Reinhoudt’s empirical rule, the intersystem crossing (ISC) process occurs when the energy gap (Δ E = 1 ππ* – 3 ππ*) exceeds 5000 cm –1 . In this case, the calculated energy gap is found to be 5529 cm –1 , surpassing the 5000 cm –1 threshold, confirming the feasibility of the ISC process. , …”

On–Off Ratiometric Fluorescence Europium(III) Metal–Organic Framework for Quantitative Detection of the Inflammatory Marker Neopterin

“…Recently, a fluorescence sensing method based on lanthanide­(III) metal–organic framework (Ln-MOF) materials has been confirmed to be a promisingly available platform for the detection of hazardous substances due to its superior sensitivity and selectivity, convenient utilization, durable reversibility, and has attracted more and more attention. − Benefiting from the unique photoluminescence behavior of the lanthanide­(III) ions and organic ligands, the effective energy-transfer processes of a fluorescence Ln-MOF material could be adapted to the regulation of the organic ligands for achieving the sensitization process via an “antenna effect”, thus achieving the simultaneous photoluminescence of lanthanide­(III) ions and organic ligands − Moreover, a fluorescence Ln-MOF material can realize the structural modifiable functionality by the encapsulation of some desired fluorescence matrix, thereby providing access to tuning the fluorescence dynamics through the influence of versatile encapsulated fluorescence matrix composites within the Ln-MOF material. − In principle, the regulations of the fluorescence Ln-MOF behaviors could be readily achieved by the optimization of fluorescence centers such as the lanthanide­(III) ions, the organic ligands, and the versatile encapsulated fluorescence matrix composites, − which endow superior applications of a Ln-MOF material for fluorescence sensing behaviors. In general, there have been two fluorescence sensing forms of the Ln-MOF material.…”

A photochromic Cd(ii)-organic framework showing highly efficient dual-response sensing properties

“…33–39 These luminescent MOF-based sensor materials for the detection of hazardous substance are mostly constructed using transition metal building centers (Zn 2+ , Cd 2+ or RE 3+ ). 40–43 It is well known that functional organic ligands play key roles in the structures and properties of MOFs. Photochromic organic molecules exhibit distinct absorption spectra before and after photoirradiation.…”
