| Outline of Final Research Achievements |
In this study, luminescent cyclic pi-conjugate systems having high two-photon absorption efficiency were constructed. First, we synthesized a macrocyclic 15-mer consisting of fluorene that can give the angle of 160 degree between dyes. This compound showed strong two-photon absorption and strong blue fluorescence. Then, a cyclic 4-mer using carbazole having the angle of 90 degree, which also exhibited strong two-photon absorption and strong green fluorescence. These componds are expected as two-photon fluorescence materials.
