Synthesis of two-dimensional π-conjugated polymers pendent with benzothiadiazole and naphtho[1,2-c：5,6-c]bis[1,2,5]thiadiazole moieties for polymer solar cells

Four new 2D donor-acceptor conjugated polymers were designed and synthesized. These new polymers comprised fluorenealt-triphenylamine or carbazole-alt-triphenylamine as the backbones, and pendants with 2,1,3-benzothiadiazole （BT） or naph- tho[1,2-c：5,6-c]bis[1,2,5]thiadiazole （NT） in a triphenylamin...
