文摘

A new strategy to synthesize 4,9- and 5,10-dialkylated 伪-aNDTs as well as 4,9- and 5,10-dialkylated 尾-aNDTs is described. Four isomeric precursors with different dithienyl-ene-diyne arrangements undergo base-induced double 6蟺-cyclization to construct the central naphthalene cores, leading to the formation of the regiospecific products. These 2,7-distannylated dialkylated aNDT-based monomers can be used for Stille cross-coupling to produce promising conjugated materials for various optoelectronic applications.
