Abstract
A straightforward synthesis of a conjugated rod/spacer/rod-type block copolymer containing PCz electron-donor and PDI electron-acceptor blocks is described. Two chromophores are covalently connected through sebacate units as saturated spacer. The resulting donor/spacer/acceptor-type block copolymer (PCz-S-PDI) can be applied to limit charge recombination between donor/acceptor interfaces and to control the scale length of nanostructure formation. PCz-S-PDI was used to produce a solar cell with the power conversion efficiency of 0.004%.
