Outline of Final Research Achievements

In this study we prepared a hexabromo derivative (1) of a propeller-shaped polycyclic aromatic hydrocarbon as a component of honeycomb two-dimensional carbon materials, and also attempted to prepare honeycomb carbon materials on metal surfaces. Firstly, we succeeded in the improvement of synthetic yield of the hexabromo derivative from 20% to 40%. Subsequently, when the polymerization reaction of 1 was carried out on a metal substrate, it was found that 1 was adsorbed in a form as if standing on the substrate, furthermore, it was found that the polymerization reaction proceeded further, giving a one-dimensional chain. In addition, we succeeded in π expansion of 1 , and also determined the rate of electron hopping between the blades of the propeller-shaped molecule and directly observed hydrogen atoms by atomic force microscopy measurements.
