“…In another work by Real and co‐worker's, a 3D dual Hoffmann type CP viz. {Fe II (3,8phen)[Au(CN) 2 ] 2 }.xPhNO 2 ( 34 ) (3,8phen=3,8‐phenanthroline, PhNO 2 =nitrobenzene) was reported [110] . The authors show an interesting example wherein the dielectric environment of the pores played a critical role in distinguishing solvents, for instance, methanol from benzene derivative.…”

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.

Cyanide is the simplest ligand with strong basicity to construct open frameworks including some of the oldest compounds reported in the history of coordination chemistry. Cyanide can form numerous cyanometallates with different transition metal ions showing diverse geometries. Rational design of robust extended networks is enabled by the strong bonding nature and high directionality of cyanide ligand. By virtue of a combination of cyanometallates and/or organic linkers, multifunctional framework materials can be targeted and readily synthesized for various applications, ranging from molecular adsorptions/separations to energy conversion and storage, and spin-crossover materials. External guest-and stimuli-responsive behaviors in cyanide-based materials are also highlighted for the development of the next-generation smart materials. In this review, an overview of the recent progress of cyanide-based multifunctional materials is presented to demonstrate the great potential of cyanide ligands in the development of modern coordination chemistry and material science.

“…Indeed, azobenzene guests have been actively used in photo‐responsive materials such as dynamic cage and metal–organic frameworks (MOFs) [6, 49–51] . Secondly, as for the SCO host, the porous Hofmann‐type Fe II MOFs provide a promising platform, in which extraordinary SCO properties, diverse pore sizes and dynamic host–guest interactions have been well documented [52–56] . In addition, loading active guest into Hofmann‐type SCO MOF is proven to be a successful strategy toward active‐guest‐dependent SCO behaviors [57] .…”

Stimuli‐responsive materials that can be reversibly switched by light are of immense interest. Among them, photo‐responsive spin crossover (SCO) complexes have great promises to combine the photoactive inputs with multifaceted outputs into switchable materials and devices. However, the reversible control the spin‐state change by photochromic guests is still challenging. Herein, we report an unprecedented guest‐driven light‐induced spin change (GD‐LISC) in a Hofmann‐type metal–organic framework (MOF), [Fe(bpn){Ag(CN)2}2]⋅azobenzene. (1, bpn=1,4‐bis(4‐pyridyl)naphthalene). The reversible trans–cis photoisomerization of azobenzene guest upon UV/Vis irradiation in the solid‐state results in the remarkable magnetic changes in a wide temperature range of 10–180 K. This finding not only establishes a new switching mechanism for SCO complexes, but also paves the way toward the development of new generation of photo‐responsive magnetic materials.
