High-Performance Vinyl-flanked Diketopyrrolopyrrole-Selenophene Polymer Semiconductors with Branching, Linear and Cyclic Alkyl Side Chains

Vinyl-containing conjugated polymers exhibiting extended conjugated skeletons with long-wavelength absorption and high carrier mobility have been widely investigated as polymer semiconductors. However, a new vinyl-flanked diketopyrrolopyrrole (DPP) unit with the...
