| | The Structures of Carbon Nanotubes in their Pristine and Oxidized Form: A quantum chemical model study | | Authors: | S. Irle and K. Morokuma | | Affilation: | Emory University, USA | | Pages: | 478 - 481 | | Keywords: | structural modifications, pristine and oxidized carbon nanotubes, [n]cyclacenes, IMOMO, density functional theory | | Abstract: | The molecular and electronic structures of pristine and oxidized [n]cyclacenes (n=6,12) as building element of (n,0) carbon nanotubes have been theoretically investigated. Geometry optimizations have been performed at the B3LYP/6-31G density functional level of theory. For larger systems with three fused [12]cyclacene macrocycles we used the integrated MO-MO (IMOMO) B3LYP/6- 31G:RHF/STO-3G level of theory. Reaction products of 1,2- and 1,4-cycloaddition reactions of oxygen atoms with the carbon skeleton served as simple model systems for oxidized systems. The calculated oxidized structures exhibit characteristic deformations as a consequence of change in carbon hybridization, leading to relaxation of ring strain in areas further away from the area of chemical modification. |  | View paper | | ISBN: | 0-9708275-6-3 |
