The Supramolecular and Coordination Chemistry of Cobalt(II) Extraction by Phosphinic Acids

Supramolecular coordination chemistry

Highlights include the formation of ultra-large macrocycles with over 200 non-hundred atoms within a given cycle. The realisation that single molecule magnetic behaviour is not limited to molecules with high spin states. The connection of S = 1/2 cluster rings using a fragment that can switch on magnetic exchange between the clusters is extremely interesting for the synthesis of QBITs and elect...

Supramolecular Chirality in Dynamic Coordination Chemistry

Labile metal complexes have a useful coordination bond; which is weaker than a covalent C–C bond and is reversibly and dynamically formed and dissociated. Such labile metal complexes also can be used to construct chiral shapes and offer dynamic conversion of chiral molecular shapes in response to external stimuli. This review provides recent examples of chirality induction and describes the dyn...

Synthesis and Coordination Chemistry of Ligands for Supramolecular Chemistry and Sensing Applications

A series of multidentate N-donor ligands have been synthesised all containing pyridyl and pyridyl/thiazole units and their coordination behaviour is described. The ligands are classified into four types; i) terpyridine containing pyridyl/thiazole ligands (L); ii) pyridyl/thiazole ligands containing a 3,3′-disubstituted bipyridine core. (L); iii) 2,2′-bipyridine containing a crown ether moiety (...

Acyclic to cyclic aminophosphonic and phosphinic acids

The results presented in this account deal with the synthesis of acyclic αor β-aminophosphonates or phosphinates and with the synthesis of heterocyclic compounds, where the phosphorus and/or the nitrogen atoms can be embedded in the heterocyclic core, showing new perspectives in bioactive molecules.
