The preparation of ortho -chelating aminoaryl ligands ([C 6 H 3 (CH 2 NMe 2 )-2-R-4] -, abbreviated as C,N) containing a pendant hydroxymethyl group is described. These ligands have been cycloplatinated with cis -PtCl 2 (DMSO) 2, yielding the corresponding C,N-platinum(II) complexes. The pendant hydroxymethyl substituent is a versatile group for attachment of the organometallic moiety to macromolecules, which has been demonstrated by attaching the C,N-platinum complexes to a dendritic wedge and to C 60 .
