Reaction chemistry of cerium [PDF]

, 1997
It is truly ironic that a synthetic organic chemist likely has far greater knowledge of the reaction chemistry of cerium(IV) than an inorganic colleague. Cerium(IV) reagents have long since been employed as oxidants in effecting a wide variety of organic

Molecular Design Strategies for High‐Voltage Organic Cathodes

Advanced Energy Materials, EarlyView.
This work proposes molecular engineering strategies for high‐voltage organic cathode materials for Li‐ion batteries: (1) increase Li‐O coordination number (CN), (2) achieve a greater increase in aromaticity upon reduction (∆Aromaticity), and (3) add an electron‐withdrawing group (EWG), through a combined experimental and computational study on reported

Reaching selective fluorescence phosphate detection over pyrophosphate with a cerium-based chemosensor in aqueous media

, 2023
Phosphate ions are important molecules used in critical activities, such as those in agriculture or medicine. However, because of their chemical makeup, sensing them using a chemosensor is difficult. In the past, chemists attempted to solve this issue by
