Dithieno[2,3‐<i>d</i>;2′,3′‐<i>d</i>′]benzo[1,2‐<i>b</i>;4,5‐<i>b</i>′]dithiophene (DTBDT) as Semiconductor for High‐Performance, Solution‐Processed Organic Field‐Effect Transistors

The facile synthesis of a new five-ring-fused pentacene analog with four symmetrically fused thiophene ring units (Dithieno[2,3-d;2′,3′-d′]benzo[1,2-b;4,5-b′]dithiophene, Cn-DTBDT) is presented. After aligning this material from solution, thin films for organic field-effect transistors were obtained, resulting in excellent hole mobilities of up to 1.7 cm2V−1s−1, and on/off ratio of 107.
