Synthesis, Characterization, and Field-Effect Transistor Performance of Pentacene Derivatives

A series of functionalized pentacene derivatives based on symmetric and asymmetric substitutions of the terminal rings are synthesized (see figure). Field‐effect mobilities as high as 0.23 cm2 V–1 s–1 are obtained with 2,3‐dibrompentacene. These devices show improved stability compared to pentacene...

Description
Summary:A series of functionalized pentacene derivatives based on symmetric and asymmetric substitutions of the terminal rings are synthesized (see figure). Field‐effect mobilities as high as 0.23 cm2 V–1 s–1 are obtained with 2,3‐dibrompentacene. These devices show improved stability compared to pentacene and exhibit no significant decrease in mobility or on/off ratio when stored in air, with and without light exposure, even after three months.
