“…were also conducted because of their various binding and bridging modes [26][27][28][29][30][31][32][33]. Not surprisingly, in a short course, biomolecules and natural products like amino acids [34][35][36][37][38][39][40][41][42][43][44][45][46], peptides [47], proteins [46], nucleobases [48], magnesium formates [49], carbohydrates [47], metal glutarates [50,51], γ-cyclodextrin [36] leaped into this mainstream as attractive precursors and soon tributaries like metal-peptide frameworks (MPFs) [47], metal-biomolecule frameworks (MBioFs) [46][47][48] surfaced out and established their niche.…”

“…Among them the perceptible appearance of amino acid derivatives in recent years, either as metal-based molecular entities or oligomeric scaffolds in MOFs or CPs, justify their inclusion in the synthon/tecton library [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48]. In this frame, structure and reactivity of different amino acids in their natural or derivatized form were extensively studied.…”

“…Advantages of amino acids are their natural framework with rich functional groups, which is amenable to derivatization thereby offering intriguing topologies when inserted as building blocks in supramolecular hierarchical self-assemblies [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. Indeed, thanks to their genuine chirality (except glycine) and electronic asymmetry, amino acid derivatives are considered as a preeminent choice to introduce asymmetry in MOFs to direct the network construction.…”

Abstract:The perceptible appearance of biomolecules as prospective building blocks in the architecture of coordination polymers (CPs) and metal-organic frameworks (MOFs) are redolent of their inclusion in the synthon/tecton library of reticular chemistry. In this frame, for the first time a synthetic strategy has been established for amine derivatization in amino acids into 1,2,4-triazoles. A set of novel 1,2,4-triazole derivatized amino acids were introduced as superlative precursors in the design of 1D coordination polymers, 2D chiral helicates and 3D metal-organic frameworks. Applications associated with these compounds are diverse and include gas adsorption-porosity partitioning, soft sacrificial matrix for morphology and phase selective cadmium oxide synthesis, Fe II spin crossover materials, zinc-β-lactamases inhibitors, logistics for generation of chiral/non-centrosymmetric networks; and thus led to a foundation of a new family of functional CPs and MOFs that are reviewed in this invited contribution.

A chiral Cu II dinuclear complex [Cu 2 (L-shis) 2 ]·4H 2 O (H 2 shis = N-salicylidenylhistidine) has been synthesized. The dinuclear units are assembled into a 3D hydrogen-bonded supramolecular structure with 1D chiral channels through hydrogen bonds between imidazole N-H groups and carboxylate oxygen atoms. 1D left-handed helical water chains in an AABB fashion, anchored through weak hydrogen-bonding

Supramolecular chemistry of Schiff base ligands and their reduced homologues is rapidly growing and gaining increased attention due to their convenient and straightforward synthetic methods and a wide range of complexation modes with almost all types of metal ions. In fact, the phenomenon of molecular recognition, self‐organization and self‐assembly, and host–guest chemistry through covalent and noncovalent interactions is pivotal to the understanding and development of supramolecular chemistry. In this direction, several forms of acyclic and macrocyclic Schiff bases and their reduced forms are employed to gain more insights and correctly ascertain the effect of different donor atoms, their relative position, the number and size of the chelating rings formed, the flexibility, and the geometry around the coordinating moiety on the molecular recognition process and selective binding of cations, anions, and/or neutral species. In this connection, this chapter deals with the supramolecular and molecular recognition properties and interesting host–guest complexes and metalla–supramolecular network structures derived from several acyclic and cyclic Schiff bases and reduced Schiff base ligands. Various solid‐state metalla‐supramolecular network structures are delineated ranging from hydrogen‐bonded linear polymers and helical coordination polymers, and 2D sheets to 3D network architectures constructed via N H⋯O, C O⋯H O solvent , O H⋯O, N H⋯O C, hydrogen bonds and C O⋯π, C H⋯π, and π–π stacking interactions. This review gives an account of the observed structural diversity in relation to the role of different donors and acceptors, aqua ligands and solvents, nature of the ligands and metal ions, and the coordination geometry around the metal ions.

Synthesis of a Self‐Assembled Molecular Capsule that Traps Pyridine Molecules by a Combination of Hydrogen Bonding and Copper(II) Coordination

Abstract: Copper(II) complexes of a tetradentate ligand self‐assemble in pyridine to form two slightly different tetrameric units. Hydrogen bonding between the tetramers forms a capsular cavity that traps four molecules of pyridine (see picture).
