| Research Abstract |
Assembly of corannulene with a bowl shaped nonplanar π-conjugated system was investigated by using its various derivatives bearing multiple peripheral substituents. Gold nanoparticles wrapped with a carbon cage composed of corannulene moieties were constructed by using the attractive multivalent interaction between gold and multiple thioether parts in the peripheral substituents of the corannulene core. SHG signals of such corannulene-attached gold nanoparticles were ~8 times more intense than those of alkanethiol modified gold nanoparticles of the same size. Inspired by the accidental observation that a newly synthesized corannulene derivative shows a mesomorphic behavior, design of the first example of liquid crystalline corannulene as well as its macroscopic alignment in response to the application of electric field was also achieved. These findings contribute the development of materials science of corannulene.
