Complementary And Self-Complementary Hydrogen Bond Double Helical Complexes, Bhanu P. Mudraboyina
Complementary And Self-Complementary Hydrogen Bond Double Helical Complexes, Bhanu P. Mudraboyina
Electronic Thesis and Dissertation Repository
The design of artificial or synthetic strands that self-assemble to form double-helical complexes have been of great interest to chemists and researchers since the discovery of the double helical DNA structure in 1953 by Watson and Crick. Most of the complexes were self-complementary double-helical homodimers and while few heterodimer complexes are also known. The present thesis describes the design, synthesis and characterization of complementary and self-complementary hydrogen bond arrays built from heterocycles such as pyridine, thiazine dioxide and indole connected in different sequences. The sequence-based stabilities, insolubility issues, substitution and preorganization effects in these arrays have been studied in detail. …

The design and characterization of linear oligomers that self-assemble into double helical structures has been a subject of interest to chemists since the elucidation of the double helix structure of DNA in 1953. Transition metal templates have been widely used in the construction of artificial double helical complexes from linear multidentate ligands. The use of other non-covalent interactions as the driving force in the self-assembly of these types of complexes is less common. Aromatic stacking interactions, anion templates, and salt-bridges have all been applied in this context. The great majority of these investigations have been concerned with the dimerization of …
