Heptafluoropentane Side Chain-Engineered Acceptor, a Morphological Modulator for High-Performance Ternary Organic Solar Cells† Shengwei Shen, Bojun Yu, Shizhao Liu, Lingya Sun, Huajun Xu, Tengxiang Gao, Chuangcheng Hong, Xunchang Wang, Jianan Zheng, Yuanyuan Kan, Wei Zhang, Guangye Zhang, Hao Cheng, Renqiang Yang, Weihua Peng, Yanna Sun, Ke Gao Chinese Journal of Chemistry, 2026 Comprehensive Summary Organic solar cells (OSCs) leveraging non‐fullerene acceptors (NFAs) have achieved power conversion efficiencies (PCEs) exceeding 20%, yet their performance critically depends on the nanoscale morphology of the bulk heterojunction (BHJ). Ternary blending is a promising strategy for enhancing photovoltaic parameters and morphology control, but simultaneously optimizing phase separation size, vertical phase distribution, and crystallinity remains challenging. Herein, a new L8‐BO‐derived non‐fullerene acceptor, namely BTP‐ HFCP, featuring a heptafluorocyclopentenyloxy–octyl side chain was developed. When it was integrated as a third component into the D18:L8‐BO binary system, BTP‐HFCP acts as an effective morphological modulator. Adv. characterizations reveal that the ternary device exhibits a significantly enhanced vertical phase distribution, optimal phase separation and balanced crystallinity, thereby improving chargecollection and reducing recombination. Consequently, the ternary OSC achieves a champion PCE of 19.32%, surpassing the binary OSC. This work demonstrates that heptafluoropentane side‐chain engineering of the third component provides a rational molecular design strategy for precise morphology control in high efficiency ternary OSCs.
Antioxidant activity and anti-melanogenic of the exopolysaccharide EPS-HuA40 from Mesonia sp. HuA40 TingTing Tang, ZhaoLi Li, YuPing Dai, BaiLu Tang, WenZhao Li, Tong Li, Hao Cheng, PingYi Li, HaiLun He Journal of Hazardous Materials Advances, 2026 • EPS-HuA40 scavenges DPPH, ·OH, and ROO· radicals effectively. • EPS-HuA40 is non-cytotoxic, reduces ROS in cells by promoting CAT/SOD production. • EPS-HuA40 inhibits B16-F10 melanogenesis by blocking tyrosinase and related genes. The growing demand for antioxidant and whitening skincare products has driven the development of eco-friendly natural ingredients. Marine microorganisms represent a rich source of novel bioactive molecules. This study investigated the antioxidant and melanogenesis-inhibitory activities of EPS-HuA40, an exopolysaccharide from the marine bacterium Mesonia sp. HuA40. EPS-HuA40 demonstrated significant dose-dependent scavenging activities against multiple free radicals, with a scavenging rate reaching up to 86.05%, which is comparable to that of the positive control antioxidant Vc (88.13%) at the same mass concentration. In HaCaT, HDF, and HUVEC cells, treatment with EPS-HuA40 significantly inhibited the production of intracellular ROS due to oxidative stress, without exhibiting cytotoxicity. And it enhanced the activities of intracellular antioxidant enzymes such as CAT and SOD to bolster cellular antioxidant capacity, protecting cells against adverse environments. Furthermore, EPS-HuA40 effectively reduced α-MSH-induced melanin production in B16-F10 cells by indirectly suppressing tyrosinase activity and downregulating melanogenesis-related gene expression. The results suggested that EPS-HuA40 exhibits significant antioxidant activity and reduces hyperpigmentation. Therefore, it holds potential for future application in skincare formulations.
