✦ Synopsis

Syn and anti cyclophanes consisting of oligothiophene units as a component have been synthesized for the first time. Correlation between the cyclophane structure and fluorescence spectral properties has been examined. Emission from intramolecular excimer-formation is confirmed for the syn cyclophanes and the mobile cyclophanes, but not for the anti cyclophanes.
