摘要：

Neutral-state black diketopyrrolopyrrole (DPP)-based conjugated polymers with the colour channels a*from -3 to 0 and b* from -2 to -7 are achieved by incorporating an additional donor segment - dialkoxythiophene (DalkOT), which leads to the enhancement in blue-wavelength absorption. The polymers display black-to-transmissive grey electrochromic switching with good redox stability.
