“…Realizing the enormous advantages of MOF-based sensors and countless harmful side effects of pharmaceutical drugs, several MOF-based drugs and antibiotics sensors are reported by many reputed research groups during the last decade. , Many review articles on antibiotic sensing based on fluorescent MOFs are already reported. ,, However, there has not been a single review article on MOF-based fluorescence sensors for small pharmaceutical drug molecules. − Therefore, it is essential to accumulate all the literature on MOF-based fluorescent sensors of pharmaceutical drugs. This is the first ever literature review which covers almost all reported MOF-based fluorescent pharmaceutical drug sensors.…”

The surging growth of clinical and pharmaceutical medication as a consequence of population growth has become a threat to the environment. The inherent antagonistic effects of medications and their metabolized side products on a healthy society is an essential concern requiring immediate monitoring. To speculate on these environmental pollutants, a huge number of selective, sensitive, costeffective, and user-compatible metal−organic framework (MOF)-based fluorescent sensors have been reported by many prominent research groups. Many recent review articles cover the details of MOF-based florescence sensing of antibiotics, but an accumulation of MOF-based fluorometric detection of other pharmaceutical drugs is still not reported. Realizing this research gap, we have discussed most of the reported MOF sensors for various pharmaceutical drugs in this Review. The details of selectivity, sensitivity (limit of detection (LOD) and Stern−Volmer constant (K sv )), response time, and proposed mechanisms of drug sensing have been thoroughly discussed. Moreover, this article also covers the details of a few MOF-based antibiotic sensors, which have not been covered by any previous report. Therefore, this Review will provide valuable information and guidance to researchers to develop targeted fluorescent sensors for hazardous pharmaceutical drugs. Additionally, environmental science researchers can leverage this information to enhance their efforts to monitor and control environmental pollution.

“…The nitroaromatic molecules bearing nitro group with strong electron-withdrawing ability are generally acceptable to be efficient electron acceptors that form fluorophores in their excited state, resulting in the emission quenching response. 42–44,51 The more sensitive probing performance towards TNP compared to DNBC (TNP bears one more nitro group) is an experimental result to support the fluorescence quenching mechanism.…”

“…To the best of our knowledge, the value of K SV stands to be the third highest among the handful of reports for MOF-based ROX sensors (Table S5). ,, The limit of detection (LOD) was estimated using the equation 3σ/m that came out as 33 nM (52 ppb). Such nanomolar detection limit endorses 22a as an ultrasensitive host for monitoring minute water-contamination of lethal ROX.…”

Stimuli-responsive emission color modulation in fluorescent metal–organic frameworks (MOFs) promises luminescence-ink-based security application, while task-specific functionality-engineered pores can aid fast-responsive, discriminative, and ultralow detection of harmful organo-aromatics in the aqueous phase. Considering practical applicability, a self-calibrated fluoro-switch between encrypted and decrypted states is best suited for antiforgery measures, whereas image-based monitoring of organo-toxins by repetitive and handy methods over multiple platforms endorses in-field sensory potential. Herein, we constructed a mixed-ligand based chemically stable and bilayered-pillar MOF from –NH2-hooked pyridyl linker and tricarboxylate ligand that embraces negatively charged [Cd3(μ2-OH)(COO)6] node and shows pore-space-partitioning by nitrogen-rich flanked organic struts. Owing to the presence of a self-calibrating triazolylamine moiety-grafted auxiliary linker, this anionic MOF delineates reversible and multicyclic fluoro-swapping between protonated-encrypted and deprotonated-decrypted domains in the alternative presence of acid and base. Such pH-triggered, site-specific luminescence variation is utilized to construct highly regenerative anticounterfeiting labels for vivid acronym encryption. The intense fluorescence signature of the material is further harnessed in extremely selective and quick responsive sensing of harmful feed additive roxarsone (ROX) and dichloran (DCNA) pesticide in highly recyclable fashion with significant quenching and nanomolar limits of detection (ROX: 52 ppb; DCNA: 26.8 ppb). Notably, the ultrasensitive fluoro-detection of both these organo-toxins is successfully demonstrated via a handy paper-strip method as well as on the vegetable surface for real-time monitoring. Comprehensive density functional theory studies validate the electron transfer mechanism through redistribution of molecular orbital energy levels by each of the targeted analytes in this electron-rich framework besides evidencing MOF-analyte supramolecular interactions.
