Mechanisms of electrochemical recognition of cations, anions and neutral guest species by redox-active receptor molecules
Abstract This short review highlights the mechanisms involved in electrochemically sensing cationic, anionic and neutral guest species by redox-active receptors and is an update to a previouslyExpand
Halogen bond anion templated assembly of an imidazolium pseudorotaxane.
The strength of chloride-anion-templated pseudorotaxane formation with a 2-bromo-functionalized imidazolium threading component and an isophthalamide macrocycle is significantly enhanced compared to hydrogen-bonded pseudorOTaxane analogues. Expand
Photosensitized Generation of Singlet Oxygen from Vinyl Linked Benzo-Crown-Ether−Bipyridyl Ruthenium(II) Complexes
Photophysical properties of 10 substituted methoxybenzene or vinyl linked benzo-crown-ether−2,2‘-bipyridyl ruthenium(II) complexes are reported. The lifetimes of the excited triplet metal to ligand...
Synthesis and Characterization of Novel Acyclic, Macrocyclic, and Calix[4]arene Ruthenium(II) Bipyridyl Receptor Molecules That Recognize and Sense Anions
The Lewis acidic redox-active and photoactive ruthenium(II) bipyridyl moiety in combination with amide (CO−NH) groups has been incorporated into acyclic, macrocyclic, and lower rim calix[4]areneExpand
Phosphate anion binding and luminescent sensing in aqueous solution by ruthenium(II) bipyridyl polyaza receptors
New ruthenium(II) bipyridyl polyaza receptors have been prepared and shown to bind and sense, via MLCT luminescent emission quenching, phosphate and ATP anions in aqueous solution.
Anion Recognition and Sensing: The State of the Art and Future Perspectives.
Anion recognition chemistry has grown from its beginnings with positively charged ammonium cryptand receptors for halide binding to a plethora of charged and neutral, cyclic and acyclic, inorganic and organic supramolecular host systems for the selective complexation, detection, and separation of anionic guest species.

Transition metal and organometallic anion complexation agents
Anions are ubiquitous species, and therefore, their sensing is of considerable interest. Anion receptors containing electrochemically active groups such as ferrocene or cobaltocenium, or opticallyExpand
