  Synthesis of Highly Soluble and Oxidatively Stable Tetraceno[2,3-b]thiophenes and Pentacenes

  摘要：

  A comparative study of suitably functionalized, highly soluble tetraceno[2,3-b]thiophenes (1-3) and pentacenes (4-6) that show higher photoxidative stability than that of unfunctionalized corresponding acenes is reported. The absorption and emission of 1-3 (A(max) = 624-656 nm, 1,lambda(max) = 634-672 nm, Phi F approximate to 10%) and 4-6 (A(max) = 672-704 nm, lambda(max) = 682-718 nm, Phi F approximate to 10%) were found to be systematically red-shifted by the substitution in the order of the tert-butylethynyl < triisopropylsilylethynyl < phenylethynyl groups. The oxidation potentials of these compounds were similar (E-1/2 approximate to 0.70 V), except for 4, which showed lower oxidation potential (E-1/2 approximate to 0.63 V).

  A convenient method for the synthesis of tetraalkylanthracenes and -pentacenes by means of ruthenium-catalyzed regioselective C-H alkylation of the corresponding acenequinones was developed. Dialkyldiarylpentacene was also synthesized using chemoselective tandem C-H alkylation/C-O arylation of dimethoxypentacenequinone. It was suggested that a tetraallrylpentacene is stable under air in the dark and possesses an appropriate HOMO level as active material for p-type organic field-effect transistors (OFETs).
