Two nonfused ring electron acceptors (NFREAs), BTh-OC8-2F and DTh-OC8-2F, with different mol. shapes are designed and synthesized. Both acceptors can form planar mol. shapes by the assistance of S閻犱警鍨甸惌鍓ф崉閻?intramol. interactions. Differently, BTh-OC8-2F, with a linear mol. backbone and two trans-arranged side chains at the core unit, exhibits much stronger crystallinity than DTh-OC8-2, with a C-shape mol. shape and two cis-arranged steric side chains at the core unit. Thus, the DTh-OC8-2F based blend film displays a better nanoscale phase separation, more suppressed charge recombination, more efficient exciton dissociation, and lower nonradiative energy loss. Organic solar cells based on DTh-OC8-2F can deliver a power conversion efficiency of 14.13%, which is much higher than BTh-OC8-2F based ones (11.95%) and is also one of the highest values reported for organic solar cells based on NFREAs. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Category: bromides-buliding-blocks).
1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Category: bromides-buliding-blocks
