Crystal engineering of novel MOF@iCOF composite as a multifunction platform for targeted monitoring and capturing of norfloxacin

Construction of carbon dots/metal–organic framework composite for ratiometric sensing of norfloxacin

“…Due to the abundant groups on the surface of the g-CDs, they are able to interact with the carboxyl group (COOH) on the surface of NFX, increasing the ability of the fluorescent material to detect norfloxacin. 31 When the g-CDs are compounded with UiO-66, the g-CDs@UiO-66 composite is rich in carboxyl and hydroxyl groups, forming strong hydrogen bonds with norfloxacin, resulting in an enhanced emission intensity.…”

The construction of dual-emissive ratiometric fluorescent probes based on fluorescent nanoparticles for the detection of metal ions and small molecules

“…[254][255][256] Fluorescence nanohybrids including lanthanide ions can be employed for the detection of sensitizers, such as TC and DPA. This type of target-sensitized new fluorescence emission was discussed in section 3.1.5 [105][106][107][108][109][110][111][112][113][114][115][116] and section 3.2.2, [212][213][214][215][216][217] and thus not emphasized in this part.…”

“…Upon the addition of DPA molecules, the red fluorescence from the sensitized Eu 3+ increased based on AE, while the blue fluorescence at 453 nm was greatly quenched through IFE. Similar complexes such as Ti 3 C 2 QDs@Eu 3+ for the detection of TC, 107 CDs@Eu 3+ for the detection of TC, 108,109 CuNCs@Eu 3+ for the detection of TC, 110 MoS 2 QDs@Eu 3+ for the detection of TC, 111 g-C 3 N 4 /Eu 3+ for the detection of DPA 112 and TC, 113 HNT@CDs@Eu 3+ for the detection of DPA, 114 LML-Eu 3+ -GMP coordination polymer for the detection of TC, 115 and MOF@COF@Tb 3+ for the detection of norfloxacin 116 have been reported. However, among the family of TCs, including CTC, TC, OTC and DC, the specific detection of each one is rather challenging due to their highly structural similarity.…”

A Europium Metal–Organic Framework and Its Polymer Composite Membrane as Switch-Off Fluorescence Sensors for Antibiotic Detection in Lake Water

“…Organic ligands as energy antennas absorb excitation light energy and transfer it to lanthanide centers to obtain high quantum yields and long fluorescence lifetimes (FLTs). Ln-MOFs have been used to detect explosives, − heavy metal cations, − volatile gases, − organic pollutants, − pesticides, − and so forth. Luminescent Ln-MOFs sensing antibiotics become a research hotspot. − …”
