<p>PURPOSE: A dikeopyrrolopyrrole polymer is provided to process solution process due to easy spin coating at a room temperature, and to have notable charge transfer and increased solubility. CONSTITUTION: A diketopyrrolopyrrole polymer is indicated as a chemical formula 1 below, and in here, R1 and R2 are (C24-50) alkyl. L1 and L2 are selected from the functional group of the chemical formula 1-a, 1-b, and 1-c below, and V is the functional group of chemical 1-d below. A1 and A2 are hydrogen, cyano, or -COOR respectively, and R' is (C1-50) alkyl or (C6-50) aryl. R3 - R8 are hydrogen, hydroxyl group, animo, (C1-50) aryl, (C1-50) alkoxy, mono or di (C1-50) alkylamino, (C1-50) alkoxycarbonyl or (C1-50) alkylcarbonyloxy respectively, and M is 1 or 2 and n is integer of 1-1,000.</p> |
