Star Polymers and Dendrimers Based on Highly Functional Resorcin- and PyrogallolarenesKrause, Tilo 28 June 2007 (has links) (PDF)
In the frame of this thesis different calix[4]resorcin- and calix[4]pyrogallolarene derivatives were used as platform for the synthesis of novel star polymers and dendritic structures. The objectives of this work can be portrayed under the following points: First: Synthesis and modification of calix[4]resorcin- and calix[4]pyrogallolarenes with a varying number and varying type of functional sites and their precise characterization by modern NMR techniques and single crystal X-ray diffraction. Second: Synthesis of well-defined star polymers and dendrimers with different number of arms and accordingly dendrons, based on calix[4]resorcin- and calix[4]pyrogallolarenes, via convenient polymerization and generation growth reactions and analysis of the obtained products by different methods (MALDI-TOF-MS, SEC-RI and SEC-MALLS, NMR).
