Abstract:
|
Supra molecular architectures of coordination complexes of liydrazones
through non covalent interactions have been explored. Molecular self—assernbly
driven by weak interactions such as hydrogen— bonding, K '”T[, C-1-I‘ "TE, van
der Waals interactions, and so forth are currently of tremendous research
interest in the fields of molecule based materials. The directional properties of
the hydrogembonding interaction associate discrete molecules into aggregate
structures that are sufficiently stable to be considered as independent chemical
species. Chemistry can borrow nature’s strategy to utilize hydrogen-bonding as
Well as other noncovalent interactions as found in secondary and tertiary
structures of proteins such as the double helix folding of DNA, hydrophobic
selflorganization of phospholipids in cell membrane etc. In supramolecular
chemistry hydrogen bonding plays an important role in forming a variety of
architectures. Thus, the wise modulation and tuning of the complementary sites
responsible for hydrogen—bond formation have led to its application in
supramolecular electronics, host-guest chemistry, self-assembly of molecular
capsules, nanotubes etc. The work presented in this thesis describes the synthesis and
characterization of metal complexes derived from some substituted
aroylhydrazones. The thesis is divided into seven chapters. |
