Synthesis and characterization of new C-60-PPV dyads containing carbazole moiety
New C-60 covalently linked PPV derivatives containing carbazole moiety poly {(2,5-di-pentoxyl-phenylene)- 1,4-diylvinylene-3,6[9-(1-azafulleroid-propyl)carbazolenevinylene]} (PPV-AFCAR) were synthesized and characterized. The polymers containing different percentage of C-60 were obtained through the percentage of azido unit being controlled by the initial feed ratio. Cyclic voltametric analysis showed that the electronic characteristic remained while it covalently attached to polymer by the cycloaddition reaction. The fluorescences of PPV moieties were strongly quenched due to the presence of fullerene.
