Supramolecular chemistry with organometallic half-sandwich complexes

Organometallic half-sandwich complexes of the late transition metals are versatile building blocks for supramolecular chemistry. They can be used to build metallamacrocyclic receptors and coordination cages, to study the adaptive behavior of dynamic combinatorial libraries and to generate indicator displacement assays for the detection of biologically interesting analytes such as peptides and aminoglycosides.
