<p>PURPOSE: A diketopyrrolopyrrole polymer is provided to have high stability of air, increased coplanarity of main chain, high solubility, and easy spin coating at a room temperature by alternation polymerizing electron acceptor and electron donor. CONSTITUTION: A diketopyrrolopyrrole polymer is indicated as a chemical formula 1 below, and from here, R1 and R2 are (C1-50) alkyl or (C6-50) aryl respectively, and L1 and L2 are selected from the functional group of the chemical formula 1-a, 1-b, a, and 1-c below. However, except the L1 and L2 are chemical formula 1-a at the same time, V is indicated as the chemical formula 1-d below, and X1-X3 are Se, O, NH or NR' respectively. A1 and A2 are hydrogen, cyano, or -COOR'' respectively, and R' and R'' are (C1-50) alkyl or (C6-50) aryl respectively. R3-R8 are hydrogen, hydroxyl group, amino, (C1-50) alkyl, (C6-50) aryl, (C1-50) alkoxy, mono or di (C1-50) alkylamino, (C1-50) alkoxycarbonyl or (C1-50) aklylcarbonyloxy.</p> |
