Description
Summary:Neutral nitrogen donor (N‐donor) ligand‐based MOFs, with their enticing features inclusive of facile synthesis, labile metal‐ligand bond, framework flexibility, atomic level tunability renders them appealing in molecular recognition‐based studies. Intriguingly, the flexibility in such systems (owing to weaker metal‐nitrogen bonds) promote maximization of host‐analyte interactions, which is critical for the manifestation of a signaling response. Such host‐analyte interactions can be tapped by discerning any change in the physical properties associated with the system, such as optical, fluorometric, chemiresistive, magnetic, dielectric constant, mass. This minireview presents a brief discussion on the various types of signal transduction pathways unveiled hitherto using neutral N‐donor ligand‐based MOFs and the fundamental insight into the signal‘s origin. Moreover, an elaborate compilation of the recent examples in this field has been presented. Also, the untapped prospects have been highlighted, which may serve as a beacon to drive future research. Neutral nitrogen donor MOFs for molecular recognition‐based studies are highlighted in this Minireview.
