Development, rapid detection and quantification of anticancer drugs in biological samples are crucial for effective drug monitoring. The present work describes the design of a metal–organic framework (MOF) between Hf(IV) ion and 2‐(thiophene‐2‐carboxamido)terephthalic acid linker (surface area = 571 m² g‐1). Desolvated 1′ displayed highly discriminative fluorescence sensing property for the anti‐neoplastic drug flutamide and biomolecule hemin in aqueous medium in the presence of co‐exiting biomolecules and ions. The MOF’s response time for sensing flutamide and hemin was less than 5 s with low detection limits 1.5 and 0.08 nM respectively. Additionally, the MOF also demonstrated recyclability up to five cycles and maintained its sensing ability across different pH media, various water samples, and biological fluids. Experimental and theoretical analyses suggested photoinduced electron transfer and inner‐filter effect in the presence of flutamide and Förster resonance energy transfer in the presence of hemin are most likely reasons behind the fluorescence quenching of MOF. Furthermore, the MOF demonstrated catalytic activity in Friedel‐Crafts alkylation reactions, providing a 96% yield with slight decay in its activity over four uses. The enhanced activity of 1′ is due to the functionalized thiophene moities through hydrogen bond donating sites, confirmed by series of control experiments.

The rising atmospheric CO 2 levels necessitate the development of effective materials for its mitigation. Utilization of adsorbent materials for the reversible physisorption of CO 2 has a significantly less impact. Recognizing this need, herein, we present a nitrogen-rich, aqua-stable, Ag(0)-nanoparticle-doped metal−organic framework (MOF) designed for the irreversible chemical conversion of CO 2 into valuable fine chemicals. We demonstrate two sustainable pathways for CO 2 fixation, utilizing the catalyst, 1′@Ag NPs. The designed catalyst facilitates the cyclization of propargylic amines and alcohols under ambient temperature and pressure conditions. Remarkably, this is the first MOF-based catalyst that allows for quantitative conversion of propargylic amines into 2-oxazolidinones at room temperature with atmospheric CO 2 pressure. The process successfully transforms various propargylic amines and alcohols into 2-oxazolidinones and α-alkylidene cyclic carbonates under the CO 2 atmosphere. Additionally, the catalyst shows excellent recyclability, maintaining its activity and structural integrity across multiple reuse cycles. Control experiments revealed that the catalytic efficiency of 1′@Ag NPs is attributed to the highly exposed alkynophilic Ag(0) sites on its pore walls. Computational studies further elucidate the mechanistic pathway for CO 2 fixation. This work highlights the potential of 1′@Ag NPs to enhance environmental sustainability by converting CO 2 into valuable bioactive chemicals under mild conditions.
