In this work, a toolbox was provided to create three-component polymer conjugates with a defined architecture, designed to bear different biocomponents that can interact with larger biological systems in biomacromolecular recognition experiments. The target architecture is the attachment of two biomolecule ‘arms’ to the alpha telechelic end point of a polymer and fixating the conjugate to the gold surface of SAW and SPR sensor chips with the polymer’s other omega chain end. This specific design of a conjugate will be implemented by using a strategy to yield novel double alpha as well as omega telechelic functionalized POx and the success of all cascade reaction steps leading to the final conjugation product will be proven through affinity measurements between covalently bound mannose and ConA. All reactions were performed on a low molecular model level first and then transferred to telechelic and also side chain functionalized polymer systems. / In der vorliegenden Arbeit wurden hydrophile Polymere und Biomakromoleküle chemoselektiv und vicinal miteinander an einer Bindungsstelle verknüpft. Die Kombination der Native Chemical Ligation (NCL) mit der Thiol–En-Reaktion stellte hierfür eine geeignete Methode dar. Ein Machbarkeitsbeweis wurde anhand einer niedermolekularen Modellreaktion erbracht und nachfolgend unter der Verwendung von Polyoxazolinen auf makromolekulare Polymersysteme übertragen. Die erfolgreiche Darstellung der Konjugate wurde durch biomakromolekulare Bindungsaffinitäts-Messungen zu dem Lektin ConA bestätigt.
