Mono‐ and difunctionalized 6,6′‐dimethyl‐2,2′‐bipyridines were introduced into polyesters in order to design polymer architectures with specific metal binding units. The polymerizations were carried out using aluminium‐alkoxide derivatives prepared by a reaction between triethylaluminium and the corresponding hydroxymethyl‐functionalized bipyridine derivatives. Polymers with narrow molecular weight distribution were obtained. The incorporation of the metal binding unit could be proven by UV/VIS‐spectroscopy and NMR‐spectroscopy.
