An extended quinoid molecule based on bis(thiophene-diketopyrrolopyrrole) with balanced ambipolar semiconducting properties and strong near-infrared absorption

A NIR strong absorbing molecule was constructed by taking the structural advantages of a quinoid and diketopyrrolopyrrole, with an absorption maximum of up to 1039 nm and hole and electron mobilities up to 0.19 and 0.2 cm 2 V −1 s −1 , respectively.
