Abstract
A stilbene derivative bearing a terminal alkyne unit has been prepared and grafted onto a Th-symmetrical C60 hexakis-adduct building block under alkyne/azide copper mediated Huisgen 1,3-dipolar cycloaddition conditions. The photophysical properties of the resulting fullerene derivative surrounded by 12 conjugated oligomers have been investigated. Upon excitation of the peripheral chromophores, an efficient intramolecular energy transfer to the C60 core has been evidenced.Keywords
