Using a Hydrogen‐Bonded Rosette‐Type Scaffold to Generate Heteronuclear Metalla‐Assemblies

Abstract

Pyridyl-functionalized melamine (MEpy) and barbituric acid (BApy) derivatives have been designed to generate rosette-type structures with multiple coordination sites. The introduction of a pyridyl group on both components (MEpy and BApy) allows coordination of metals at the periphery of the (MEpy) 3 ·(BApy) 3 rosette. Dichloro para-cymene ruthenium and

Stimuli‐Responsive Self‐Sorting Hybrid Hydrogen‐Bonded/Metal‐Coordinated Cage

“…We hypothesised that using hydrogen‐bonded rosette motif [22, 23] and palladium(II)/platinum(II) coordination to a pyridine ligand could lead to a preparation of such hybrid hydrogen‐bonded/metal‐coordinated cage (Figure 1). The rosette motif as well as other hydrogen‐bonded motifs has been successfully utilised for a preparation of various hybrid hydrogen‐bonded/metal‐coordinated complexes (mostly 2D) [22–30] . Here, we report the self‐assembly, characterisation and the unique stimuli‐responsive behaviour of a genuine hybrid cage.…”

Hydrogen-Bonded Supramolecular Architecture by Solvomorphism of Hexahydroxytriptindane: From a Rosette Network to a Rod Structure

“…Construction of hydrogen-bonded rosettes is one of the emerging fields in supramolecular chemistry. Its potential applications are rich in various realms, including supramolecular assembly − and crystal engineering . Over the past few decades, chemists have employed symmetrical cations and anions as building blocks to assemble rosette layers. − Another commonly used strategy is the use of heterocyclic molecules equipped with suitable hydrogen-bonded arrays for a preorganized assembly. − Based on the matching of donor and acceptor patterns, a variety of homomeric or heteromeric rosettes have been prepared.…”
