Isomeric indacenedibenzothiophenes: Synthesis, photoelectric properties and ambipolar semiconductivity

Article abstract of DOI:10.1039/c6tc01808d

A new strategy via double C-H activation cyclization has been developed for the versatile synthesis of IDBT derivatives with quite different photoelectric properties. Single-crystal field-effect transistors based on IDBT-l-TIPSA delivered high and balanced charge carrier mobilities of up to 0.64 cm² V^-1 s^-1 for holes and 0.34 cm² V^-1 s^-1 for electrons under ambient conditions.
