Design, Synthesis, and Characterization of [1 → 3]; [1 → (2 + 1 Me)]; [1 → (2 + 1)] C-Branched Dendrons and Dendritic Architectures
Year: 2006
Type: article
Abstract: Various dendrons and dendrimers with [1 → 3]; [1 → (2 + 1 Me)]; [1 → (2 + 1)] C-branching were designed, synthesized, and studied.Dendrimers with internal PEG linkages were prepared using a convergent approach.Incorporation of triethylene glycol units within the dendritic framework rendered the dendrimer soluble in both polar and apolar solvents.The solubility of lithium triflate salts in chloroform in the presence of PEGed dendrimers is described.Dendrimers from 1 st to 5 th generation with [1 → (2 + 1 Me)]-C-branched monomer were constructed by iterative methodology.Quantum dots were prepared in the presence of 1 st -5 th generation dendrimers and their emission properties studied.The synthesis of cyano-terminated, sol-gel dendrons and their application in capillary microextraction-gas chromatography (CME-GC) are described.A convenient synthesis for the construction of [1 → 3]-C-branched dendrons was developed.The design and synthesis of conifer-shaped dendritic architecture as well as its complexation with β-cyclodextrin are described.1 H NMR, 13 C NMR, IR, ESI-MS, and MALDI-TOF MS methods were used to characterize all new intermediates and final products.Potential applications of these dendrons and dendrimers, as polymer electrolytes, solid sorbents, and the unimolecular micelles are envisioned.iv ACKNOWLEDGMENTS I would first like to thank Professor George R. Newkome for being a wonderful advisor during my time at The University of Akron.Professor Newkome is a tremendous chemist from whom I have learned a great deal.He is also the most creative person I have ever met in a chemistry lab and I will never forget witnessing his many brilliant ideas.But more importantly Professor Newkome is a wonderful person.He has created an extremely positive and encouraging work environment that makes it a pleasure to come to work everyday.I am indebted to Dr. Charles N. Moorefield for his detailed assistance with laboratory techniques.
