摘要

An alternative synthetic route for the preparation of key intermediate synthons 7--bromoacetyl-2-diphenylaminofluorene (-BrDPAF-H) and 7--bromoacetyl-9,9-dialkyl-2-diphenylaminofluorene (-BrDPAF-Cn) was demonstrated. The latter reactions involved the first step of dialkylation of 2-bromofluorene at C9 position of the fluorene moiety, the second step of a diphenylamino group attachment at C2 position of the resulting dialkylfluorene, and the third step of Friedel-Craft acylation of -bromoacetyl group at C7 position of dialkylated diphenylaminofluorene. From the intermediates -BrDPAF-H and -BrDPAF-Cn, a series of C60-keto-DPAF nanostructures, such as the fullerene monoadducts C60(>DPAF-H) and C60(>DPAF-Cn), where n is 2, 4, or 10, were synthesized in a reasonable yield. Molecular mass ions of the dyads C60(>DPAF-H), C60(>DPAF-C2), C60(>DPAF-C4), and C60(>DPAF-C10) were clearly detected in positive ion matrix-assisted laser desorption ionization mass spectrum (MALDI-MS) that confirmed the composition mass of each compound synthesized.
