Abstract:
Using benzo-15-crown-5 derivatives as starting materials, two novel benzo-15-crown-5/C60 dyads with different linking chains were designed and synthesized in good yields by 1,3-dipolar cycloaddition of azomethine ylide generated in situ from aldehyde and sarcosine tied to C60. It was found their UV-Vis absorption spectra could be regulated hypsochromically by metal ions complexation. The long and soft linking chain was favorable for cooperate interaction of crown ether unit and C60 unit.
