A Thermally Stable Semiconducting Polymer

A Thermally Stable Semiconducting Polymer

The thermal stability of the poly(2,7‐carbazole) derivative (PCDTBT) is investigated. UV–visible absorption spectra and X‐ray photoelectron spectroscopy data demonstrate that the electronic structure of PCDTBT is stable in air at annealing temperatures up to 150 °C and in N2 even after exposure to t...

Zusammenfassung:The thermal stability of the poly(2,7‐carbazole) derivative (PCDTBT) is investigated. UV–visible absorption spectra and X‐ray photoelectron spectroscopy data demonstrate that the electronic structure of PCDTBT is stable in air at annealing temperatures up to 150 °C and in N2 even after exposure to temperatures up to 350 °C. Field‐effect transistors fabricated with PCDTBT show stable characteristics and hole mobility up to 150 °C (air) and 350 °C (N2).
