6-Azafulleroid-6-deoxy-2,3-di-O-myristoylcellulose (3) was synthesized from 6-azido-6-deoxycellulose (1) by two reaction steps. The myristoylation of compound 1 with myristoyl chloride/pyridine proceeded smoothly to give 6-azido-6-deoxy-2,3-di-O-myristoylcellulose (2) in 97.0% yield. The reaction of compound 2 with fullerene (C_60) was carried out by microwave heating to afford compound 3 in high yield. It was found from FT-IR, [13]C NMR, UV-vis, differential pulse voltammetry (DPV), SEC analyses that compound 3 was the expected C_60-containing polymer. Consequently, maximum degree of substitution of C_60 (DS_{C60}) of compound 3 was 0.33.
