Abstract
|
<B>Summary:</B> Polypeptide-shelled poly(propylene imine) dendrimers were realized by ring-opening polymerization of <I><IMGSRC="/giflibrary/12/alpha.gif"BORDER="0"></I>-amino acid <I>N</I>-carboxyanhydrides, initiated by dendrimers as core molecules. Polypeptides with 2nd generation core were used as model compounds to investigate interior complexes between metal ion and surface-modified dendrimers. Micro-calorimetric measurements outlined the formation of approximate 1:1 complexes between Cu<SUP>II</SUP> and polypeptide-shelled dendrimers and the influence of polypeptide chain compositions on differential molar heats of complexation.
