Abstract

The present invention is generally directed to a polymeric metal complex comprising a polymeric material having a plurality of a first-type functional groups, wherein at least a portion of the functional groups are coordinated to at least one metal containing complex, polymeric-metal complex salts comprising at least one polymeric material having a plurality of first-type functional groups having a charge, and at least one metal complex having an opposite charge. It further relates to devices that are made with the polymeric metal complex or the polymeric-metal complex salt.
