摘要：

Arylene linkers in a series of new tetraazabenzodifluoranthene diimide dimers enable tuning of the 3D molecular structure of nonfullerene electron acceptors, facilitating observation of dramatic variation of the power conversion efficiency from 2.6% to 6.4% as the twist angle between the monomeric building blocks in the dimer is varied. © 2015 WILEY-VCH Verlag GmbH & Co.
