Organic thin film transistors

The synthesis of two a,a -disubstituted bis(dithienothiophene) (BDT) derivatives 163 and 166 for organic thin film transistors (TFT) has been performed. Substitution of dithienodithiophene 15 and subsequent oxidation with -BuLi and Fc(acac) gave the two derivatives (Scheme 18) <1999SM(102)987>. 

The a,a-disubstituted bis(dithienothiophene)derivatives 116 (Table 2) have been deposited as active layers in organic thin-film transistors <1999SM(102)987>.
