Fused ring non-fullerene acceptors with benzothiophene dioxide end groups and their side chain effect investigations

The development of small molecule-based non-fullerene acceptors (NF-SMAs) greatly advanced the performances of polymer solar cells (PSCs) in recent years. As the foreseeability of commercializing this technology in the future, interest in reducing the materials cost is rising. To this end, efforts have been made in this work on exploring the usage of commercially available chemical segment of benzothiophene dioxide (BC) in constructing efficient NF-SMAs. Thus, we designed and synthesized two BC-based NF-SMAs, which showed high power conversion efficiency (PCE) of 7.59% also by device engineering and side chain engineering. Our work revealed the full potential of using BC end groups in constructing high-performance NF-SMAs and demonstrated the application of side chain engineering in tuning material properties and performances.

Method for preparing disperse blue 354

The invention discloses a method for preparing disperse blue 354. The method comprises the following steps: using dichloroethane as a reaction solvent, carbonyl iron powder as a catalyst, 3(2H)-indanone sulfur-1,1-dioxide and malononitrile as reaction raw materials, and obtaining an intermediate nitrile compound through a cyanation reaction; putting acetic acid, the intermediate nitrile compound, 2-methyl-4-aminobenzaldehyde and phosphoric acid into a reaction container to be stirred uniformly, then adding aluminum trichloride, putting bromohexane into a reaction system of a condensation section through a condensation reaction, and thus obtaining a target product through an alkylation reaction. A raw material 4-(N,N-dihexyl amino)-2-tolyl aldehyde is replaced with the 2-methyl-4-aminobenzaldehyde and the bromohexane; although one reaction is added, the added alkylation reaction and the condensation reaction are in the same system, and the operation difficulty coefficient is not added additionally; more importantly, the change of the technology promotes the process of the reaction to be more thorough, the yield of the product is further improved, and the total yield is 84% or more than 84%; and more importantly, industrialization is easy to realize, and the unit consumption of the product is reduced.
