Abstract

Using polyhedral oligomeric silsesquioxane (POSS) as starting material, novel dumbbell-shaped POSS-C60 dyads with flexible spacers were designed and synthesized in good yields by esterification, subsequent etherification, and further 1,3-dipolar cycloaddition of azomethine ylide generated in situ from aldehyde and sarcosine to C60.
