Side‐Chain Engineering of Y‐Series Acceptors with Halogenated End‐Group for Efficient Indoor Organic Photovoltaics

Muhammad Ahsan Saeed, Hyeon Su Kim, Gyeong Min Lee, Hyungju Ahn et autres

Abstract Diverse design strategies for nonfullerene acceptors (NFAs) have aided the development of efficient indoor organic photovoltaics (OPVs) for Internet‐of‐things‐enabled gadgets. However, the side‐chain approach to Y‐series NFAs for fabricating indoor OPVs remains largely unexplored. In this study, the synthesis and photovoltaic …

Unsual Cytotoxic Phenethylamides form Xenerhabdus nemetophilus

Seon Guk Baek, Yeong Hwan Park, Seung Il Seo, Hyeon Su Kim et autres

Three simple carboxamides incorporating the phenethylamine moiety have been isolated from strain XR-NC of a symbiotic bacterium Xenorhabdus nematophilus. Their structures were identified by spectroscopic data and synthesis. The compounds exhibited significant cytotoxicities against human cancer-cell line, viz. the gastric adenocarcinoma, colon …
