Reverse evolution of fluorine and side chains in bisisoindigo‐based copolymers enabling electron mobility exceeding 7 cm2·V−1·s−1

FlexMat, EarlyView.
Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, and thus charge ...

Development of an Efficient and Scalable Process for Preparing Timolol N‐Nitrosamine Impurities B, C, E, H, I, J, and Their ADMET Evaluation

Journal of Heterocyclic Chemistry, EarlyView.
N‐nitrosamine impurities (B, C, E, H, I, J) of timolol maleate are easily synthesized from diethyl malonate and 3,4‐dichloro‐1,2,5‐thiadiazole. Good yields and precise impurity profiling are made possible by the effective technique, which also ensures pharmaceutical safety and strengthens regulatory compliance.
