Theoretical Study for the Preparation of New Buckyballs from the Cyclic Dimerization Reaction of Two Molecules Corannulene, Coronene and Circulene Aromatic Compounds
Dr.Hasan R. Obayes

Corannulene, coronene and circulene are polycyclic aromatic hydrocarbons (PAHs) compounds were chosen in this research to study the preparation of new buckyballs with diameters smaller fraction of nano-meter theoretically may achievable using the density function theory (DFT). The results showed that the shapes of stable molecules are; corannulene molecule is bowl-shaped, coronene molecule is planar, circulene molecule has a unique saddle-shaped structure. Upon to cyclic dimerization reaction for two of the molecules selected resulting a new buckyballs formation. The results showed that the new buckyballs prepared have high efficiency in the gap energy, making it potentially useful for solar cell applications.
