| Research Abstract |
Because of the interest in the unique electronic features of molecules with large conjugated structures, synthesis of large polycyclic aromatic hydrocarbons through the expansion of a ring-fused structure has recently been widely studied. On the other hand, in this research, a series of novel, large conjugated cyclic molecules were constructed by connecting small aromatic molecules via (a) C-C or (b) Si-Si single bonds. Through rational design of the angle and connection formed, sheet, tube, and step-like conjugated structures were constructed. As a results a series of new molecules with outstanding characteristics were developed: One of the molecules had an extremely high thermal stability with an enhanced ability to delocalize spin and charge, and it was a good carrier transporter in organic light-emitting diode (OLED) devices.
