Abstract:
In this work, dithieno[3,2-a:3',2'-j][5,6,11,12]chrysene diimides (DTCDI), an electron-deficient π-building block, were firstly incorporated into polymer main chains by using the 3,9-positions of chrysene and the α,α'-positions of thiophene units of DTCDI to connect with the 2,2'-bithiophene unit, affording copolymers P1 and P2, respectively. Due to their different connection ways the two polymers feature different optoelectronic properties.
