Thiadiazoloquinoxaline–Acetylene Containing Polymers as Semiconductors in Ambipolar Field Effect Transistors

Thiadiazoloquinoxaline–Acetylene Containing Polymers as Semiconductors in Ambipolar Field Effect Transistors

Two conjugated copolymers, PPTQT and PTTQT, were developed based on thiadiazoloquinoxalines connected via ethynylene π-spacer to thiophene units. PPTQT showed maximum hole and electron mobility of 0.028 and 0.042 cm2/V s, respectively, being the first example of an ambipolar semiconducting material...

Zusammenfassung:Two conjugated copolymers, PPTQT and PTTQT, were developed based on thiadiazoloquinoxalines connected via ethynylene π-spacer to thiophene units. PPTQT showed maximum hole and electron mobility of 0.028 and 0.042 cm2/V s, respectively, being the first example of an ambipolar semiconducting material bearing triple bonds in the polymer backbone.
