Research Abstract

The obective of this research proect is to develop organic semiconductors responsive to mechanical stimuli. Bisphenylethynylbithiophene and bisphenylethynylterthiophene derivatives which exhibit phase transitions by shearing stress were synthesized and their photoconductive behaviors were studied. Moreover, donoracceptor type liquid crystals which exhibit ambipolar transport and liquid crystalline oligothiophene derivatives bearing branched alkyl chains were investigated.
