A bundle-shaped nano-supramolecular assembly possessing numerous luminescent cyclodextrin-Tb polyads and photosensitizing C(60) units has been constructed through the end-to-end inclusion complexation of cyclodextrin cavities with C(60)s, and its properties have been comprehensively characterized. Further investigations on the luminescence properties of the cyclodextrin-Tb polyad and the bundle-shaped assembly demonstrate that a pyridine --> Tb --> C(60) intramolecular energy transfer process is operative when a solution of the assembly is exposed to UV light.
