A new dithieno[3,2-b:2′,3′-d]thiophene derivative for high performance single crystal organic field-effect transistors and UV-sensitive phototransistors

Abstract

2,6-DADTT was presented, demonstrating a mobility up to 1.26 cm2 V−1 s−1 and a photosensitivity (P) of 2.49 × 106, a photoresponsivity (R) of 6.84 × 103 A W−1, and ultrahigh detectivity (D*) of 4.70 × 1016 Jones to UV light.
