两个二酮吡咯并吡咯二聚体具有不同的低聚亚甲基系链长度表现出不同的聚集行为，导致与PC61BM混合时的相分离程度的显着差异。尽管具有几乎相同的光学性质，但由于相分离的差异，它们与PC61BM的共混膜在体异质结太阳能电池中表现出不同的功率转换效率。
Two diketopyrrolopyrrole dimers with different oligomethylene tether length showed distinct aggregation behaviours, leading to a significant difference in the degree of phase separation upon mixing with PC61BM. Despite almost same optical properties, their blend films with PC61BM exhibited distinct power conversion efficiency in bulk‐heterojunction solar cells as a result of difference in phase separation.
