06.06.2015 Thermal stability of hexaprismane C12H12 and octaprismane C16H16
The results of quantum-mechanical calculations of elementary prismanes—hexaprismane C12H12 and octaprismane C16H16—have been presented. Their stability has been investigated in terms of the density functional theory and nonorthogonal tight-binding model, and the heights of potential barriers preventing isomerization and decay have been determined. It has been established based on the analysis of the molecular dynamics data and the hypersurface of the potential energy of these metastable compounds that hexaprismane and octaprismane have a rather high kinetic stability, which indicates the possibility of the formation of carbon polyprismanes for applications in microelectronics and nanoelectronics, power engineering, pharmaceutics, metrology, and information technologies.
