“…During the sensing process, the detection mechanisms of LMOFs sensors may be diverse and complex, mainly involving photo-induced electron transfer (PET), − resonance energy transfer, competitive absorption (CA), − structural transition (ST), and chemical transformation . The possible fluorescence response mechanisms of compound 1 to these four phenolic organic small molecules were investigated.…”

Hexachlorocyclotriphosphazene is one of the most representative phosphazene compounds which have been proved to have broad application prospects in many fields. However, it is an emerging research perspective to combine cyclotriphosphazene-derived polycarboxylic acid compounds with lanthanides for the construction of Tb-DPCP metal−organic f r a m e w o r k ( M O F ) m a t e r i a l s . H e r e i n , a T b -D P 1), was successfully prepared via the reaction of H 12 HDPCP [hexa(4-carboxyphenoxy) cyclotriphosphazene] and Tb(NO 3 ) 3 •6H 2 O under the solvothermal condition. Through fluorescence sensing experiments, it was found that both nitrophenols and chlorophenols could cause the fluorescence quenching of compound 1. At the same time, the compound also exhibited nice trace detection ability for small-molecule drugs (moxifloxacin hydrochloride, balsalazide disodium, and colchicine); the limits of detection were all lower than 0.2 μM. These experimental results fully demonstrated the potential application value of 1 as a multifunctional fluorescent sensor.

“…However, they are considered major organic pollutants in water that cause various health issues, such as immunity decline, allergic reactions, hereditary genetic defects, and cancers [49][50] . Nitro-aromatics, which are the primary components of explosives, pose several health and environmental problems because of their high water solubility and low vapor pressure 51 . Mycotoxins, which are secondary metabolites formed by filamentous fungi growing on organic material, are known for their potential threat to human and animal health 52 .…”
