摘要:
                                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. (C) 2009 Elsevier Ltd. All rights reserved.
