Abstract

Abstract A new high-performing small molecule n-channel semiconductor based on diketopyrrolopyrrole (DPP), 2, 2′-(5, 5′-(2, 5-bis (2-ethylhexyl)-3, 6-dioxo-2, 3, 5, 6- tetrahydropyrrolo [3, 4-c] pyrrole-1, 4-diyl) bis (thiophene-5, 2-diyl)) bis (methan-1-yl-1- ylidene) dimalononitrile (DPP-T-DCV), is successfully synthesized. The frontier molecular orbitals in this designed structure are elaborately tuned by introducing a strong electron- ...
