High-Performance Solution-Processable N-Shaped Organic Semiconducting Materials with Stabilized Crystal Phase

N‐shaped organic semiconductors are synthesized via four steps from a readily available starting material. Such semiconductors exhibit preferable ionization potential for p‐type operation, thermally stable crystalline phase over 200 °C, and high carrier mobility up to 16 cm2 V–1 s–1 (12.1 cm2 V–1 s–...

Description
Summary:N‐shaped organic semiconductors are synthesized via four steps from a readily available starting material. Such semiconductors exhibit preferable ionization potential for p‐type operation, thermally stable crystalline phase over 200 °C, and high carrier mobility up to 16 cm2 V–1 s–1 (12.1 cm2 V–1 s–1 on average) with small threshold voltages in solution‐crystallized field‐effect transistors.
