High-Performance Ambipolar Polymers Based on Electron-Withdrawing Group Substituted Bay-Annulated Indigo

For donor–acceptor conjugated polymers, it is an effective strategy to improve their electron mobilities by introducing electron-withdrawing groups (EWGs, such as F, Cl, or CF3) into the polymer backbone. However, the introduction of different EWGs always requires a different synthetic approach, leading to additional arduous work. Here, an effective two-step method is developed to obtain EWG substituted bay-annulated indigo (BAI) units. This method is effective to introduce various EWGs (F, Cl, or CF3) into BAI at different substituted positions. Based on this method, EWG substituted BAI acceptors, including 2FBAI, 2ClBAI, and 2CF3BAI, are reported for the first time. Furthermore, four polymers of PBAI-V, P2FBAI-V, P2ClBAI-V, and P4OBAI-V are developed. All the polymers show ambipolar transport properties. Particularly, P2ClBAI-V exhibits remarkable hole and electron mobilities of 4.04 and 1.46 cm2 V?1 s?1, respectively. These mobilities are among the highest values for BAI-based polymers.

Styrene monooxygenase from Pseudomonas sp. LQ26 catalyzes the asymmetric epoxidation of both conjugated and unconjugated alkenes

A novel styrene monooxygenase (SMO) was isolated from Pseudomonas sp. LQ26, a styrene degrader from activated sludge. Sequence alignment demonstrated that it was the most distant member of all SMOs originating from the genus of Pseudomonas. The substrate spectrum of this enzyme extended beyond typical SMO substrates to 1-allylbenzene analogues, previously reported as non-substrates for the SMO from Pseudomonas fluorescens ST. The results demonstrate for the first time the asymmetric epoxidation of both conjugated and unconjugated alkenes catalyzed by SMO and suggest that a much broader substrate spectrum is expected for SMOs.
