First generation (G1) and prototypical second generation (G2’) Type IIIB Rotaxane Dendrimer, which incorporate rotaxane features as the branching units, were synthesized by employing consecutive (1) modified Copper-Catalyzed Alkyne-Azide Cycloaddition (CuAAC), (2) amide formation through stopper molecule and pseudorotaxanes, and (3) GlaserHay’s acetylene homo-coupling reaction. Pseudorotaxanes with ammonium thread and crown ether macrocycle were employed. The Type III-B Rotaxane Dendrimers were characterized by nuclear magnetic resonance (NMR) spectroscopy, electrospray ionisationmass spectrometry (ESI-MS). This study provides an indispensable prototype to the synthesis of novel Type III-B Rotaxane Dendrimer. It opened up great opportunity for supramolecular and polymer chemists to further explore the properties and biomedical and electronic application of the novel dendrimers. / Detailed summary in vernacular field only. / Ho, Kwok Wai. / "October 2012." / Thesis (M.Phil.)--Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves 49-51). / Abstracts also in Chinese. / Contents --- p.i / Acknowledgments --- p.ii / Abstract --- p.iii / Abbreviations and Acronyms --- p.v / Synthetic Studies Towards Type III-B Rotaxane Dendrimer / Chapter Chapter 1 --- Introduction / Chapter 1.1 --- Classification of Rotaxane Dendrimers --- p.2 / Chapter 1.2 --- Type II-B Rotaxane Dendrimer --- p.5 / Chapter 1.3 --- Application of Copper Catalyzed Alkyne Azide Cycloaddtion(CuAAC) in Rotaxane Synthesis --- p.8 / Chapter 1.4 --- Potential Application of Type III-B Rotaxane Dendrimer --- p.12 / Chapter 1.5 --- Aim of Project --- p.14 / Chapter Chapter 2 --- Synthetic Studies Towards of Type III-B Rotaxane Dendrimer / Chapter 2.1 --- Design and Synthesis of Type III-B Rotaxane Dendrimer --- p.15 / Chapter 2.2 --- Characterization of G1 and G2’ Type III-B Rotaxane Dendron/Dendrimer --- p.27 / Chapter 2.2.1 --- ¹H NMR Spectroscopy --- p.27 / Chapter 2.2.2 --- ¹³C NMR Spectroscopy --- p.32 / Chapter 2.2.3 --- Mass Spectrometry --- p.32 / Chapter 2.3 --- Conclusion --- p.38 / Chapter Chapter 3 --- Experimental Procedures / Chapter 3.1 --- General Information --- p.39 / Chapter 3.2 --- Experimental Procedures --- p.40 / References / Appendix / List of Spectra --- p.A1
