Structural And Electronic Properties

The structural and electronic properties of 3'(4-(5-oxo-5-piperidin1-1-yl)penta-1,3-dienyl)benzo[d][1,3]dioxol-2-yl]-thymidine molecule have been investigated theoretically by performing density functional theory (DFT/3-21G*, 6-31G* and 6-31G**). The geometry of the molecule is optimized, and the electronic properties and relative energies of the molecules have been calculated by density functional theory in the ground state. The resultant dipole moments of the studied molecule are about 5.5, 6.36 and 7.35 Debyes by three levels (3-21G*, 6-31G* and 6-31G**, respectively). This property makes it an active molecule with its environment that is this molecule may interacts with its environment strongly in solution.Keywords:  3'-Azido-3'-deoxythymidine (AZT); Piperine; Density functional theory (DFT); Thymidine.© 2011 JSR Publications.

And Control

The structural and electronic properties of functionalized graphyne were studied by using density functional theory. Different concentrations of CCl2 molecules were added to α-graphyne and β-graphyne sheets. The high binding energies indicated the strong adsorption of CCl2 molecules on graphyne sheets. It was found that functionalization with CCl2 molecules can open a band gap in graphyne and functionalized graphyne sheets showing semiconducting properties. The band gap of graphyne was dependent on the concentration of adsorbed CCl2 molecules. Our results indicated that chemical functionalization of graphyne with CCl2 groups could be an effective method to modify and control the electronic properties of graphyne.
