  Synthetic Approach to and Characterization of a Fullerene-DTBT-Fullerene Triad

  摘要：

  The synthesis of a new fullerene-dithienylbenzo[c]thiophene (DTBT)-fullerene triad is reported. The synthetic approach involves the synthesis of a DTBT unit, a Sonogashira reaction to introduce two acetylenic groups, and the coupling with fullerene. The product showed an absorption at lambda = 485 nm and a fluorescence band at lambda = 575 nm.

  A systematic study on the regioselective cyclization of benzene- and naphthalene-based unsymmetrical diols with HBr (33 %) in acetic acid at room temperature led to the formation of annulation products. By using this method, synthesis of a wide variety of anthracene, tetracene and naphtho[b]thiophene analogues was achieved in good to excellent yields. By employing HBr (33 %) in acetic acid as a catalyst

  [Graphics]A Bronsted acid-catalyzed highly efficient construction,of substituted arylanthracenes and heteroacenes is described, which is assumed to be initiated through the facile formation of a benzylic cation intermediate. This method offers several advantages in comparison with known aromatic cyclodehydration reactions such as high selectivities, mild reaction conditions, and easily accessible starting materials.

  The synthesis of a new fullerene - dithienylbenzo[c]thiophene (DTBT) - fullerene triad has been reported. The synthetic scheme provides the synthesis of DTBT unit, a Sonogashira reaction to introduce two acetylenic groups and the coupling with fullerene. The product showed an absorption at 485 rim and a fluorescence band at 575 nm. Treatment of 5-(3-(5-ethynyl-2-thienyl)benzo[c]-1-thienyl)thiophene-2-carbaldehyde with LHDMS gave a dimeric product that showed an absorption at 475 nm and a fluorescence band at 595 nm. Furthermore, 5-(3-(2-thienyl)benzo[c]-1-thienyl)thiophene-2-carbaldehyde was treated with hydrazine to give the corresponding adduct that showed an absorption at 480 nm and a fluorescence band at 605 rim.
