A number of new amino-diphosphine ligands have been prepared with tethering groups allowing attachment to porous silica supports. The formation of Ni(0) complexes, allows the preparation of catalytic intermediates in the conversion of CO2 and other small molecules into useful chemical feedstocks. We describe further a set of tetherable hydroxamic acid and aminopyridyl ligands which may be attached to responsive polymers for ratiometric sensing of iron, copper and zinc. These ligands display redox-selection and size-selection properties which allow sensitive analyte detection.
