Synthesis of tetraselenophenoporphyrazine and its application in transistor devices

Abstract

We report the first synthesis of a soluble selenophene containing porphyrazine derivative, tetraselenophenoporphyrazine (SePz). Thin films of SePz exhibit a broad and strong absorption in the visible to near-IR region, which is red shifted compared to the thiophene analogue, and demonstrate p-type carrier mobilities of 10⁻² cm² V⁻¹ s⁻¹ in bottom gate, bottom contact field effect transistors.
