Outline of Final Research Achievements

Electric measurement of single molecules which pi-systems were altered by external stimuli such as heat, light, acid, etc. was planned. Bicyclo[2.2.2]octadiene ring system was chosen as such an external-stimulus-changeable moiety and porphyrin, and hexapyrrolohexaazacoronene (HPHAC) were chosen as such pi-systems.　In bisthiaporphyrins fused with BCOD and benzene rings, their macrocyclic ring current routes were altered from on a long axis to on short axes by protonation.
