ABSTRACT:
Unique, valuable and multifariously utile macromolecular complexes are comprised of: (i) non-ionic, amidocarbonylic, water-soluble polymers (and, for some embodimental purposes, the monomeric precursor(s) thereof), including such known materials as (poly)N-vinylpyrrolidone (i.e., "PVP") and/or (poly)N-vinyl-5-methyl-2-oxazolidinone (i.e., "PVO-M") and the hereinafter disclosed like(s) and/or equivalent(s) thereof which, for convenience, may be herein generically identified as "WSP"; and (ii) square planar configured platinous and, for instant applicancy, equivalently metalled organometallic compounds characterized in containing in ligandal inclusion an aromatic moiety from which depends and to which is connected at least a single distinctly polar substituent group (or "handle", as it were), such as an hydroxide (i.e., "--OH"), carboxylic acid (i.e., "--COOH") or sulfonic acid - (i.e., "--SO.sub.3 H") unit and/or equivalents thereof as herein disclosed which, for convenience, may for generic identification be herein called an "SPOM". The WSP:SPOM complex(es) are associated by non-ionic or other bonding attachment in the nature of hydrogen bonding and/or closely related electrostatic interaction between or through and to the polar substituent in the SPOM and the amidocarbonylic unit in the WSP.
