| Outline of Final Research Achievements |
The purpose of this research was to disclose effect of curved structures on molecular functionalities compared with planar pi-conjugated molecules. As a result, we discovered unique supramolecular assemblies based on curved pi-conjugated molecules. In particular, we have achieved a creation of novel two-photon absorption switching host-guest molecules based on azabuckybowl and C60. In addition, we found a formation of supramolecular polymer with azabuckybowl dimer in the presence of stoichiometric amount of C60. These phenomena have not been reported for planar pi-conjugated molecules.
Secondly, stimuli-responsibilities of three-dimentional molecules have been developed by dimerization of hexa-peri-hexabenzocoronene. The dicyanoethano-bridged dimer exhibited mechanochromic behaviors. Furthermore, fluoromechanochromism was also observed for the dicyanoetheno-bridged dimer. These results would lead to creation of novel molecular sensors based on curved pi-conjugated molecules.
