Fluorine-Containing Drugs Approved by the FDA in 2018.

Chemistry, 2019
Over the last two decades, fluorine substitution has become one of the essential structural traits in modern pharmaceuticals. Thus, about half of the most successful drugs (blockbuster drugs) contain fluorine atom.

Self‐Protective Room‐Temperature Phosphorescence of Fluorine and Nitrogen Codoped Carbon Dots

Advanced Functional Materials, 2018
The unstable triplet excited state is a core problem when developing self‐protective room temperature phosphorescence (RTP) in carbon dots (CDs). Here, fluorine and nitrogen codoped carbon dots (FNCDs) with long‐lived triplet excited states, emitting pH ...

Transition-Metal-Mediated and -Catalyzed C-F Bond Activation by Fluorine Elimination.

Angewandte Chemie, 2018
The activation of carbon-fluorine (C-F) bonds is an important topic in synthetic organic chemistry. Metal-mediated and -catalyzed elimination of β- or α-fluorine proceeds under milder conditions than oxidative addition to C-F bonds.

Electrochemically Scalable Production of Fluorine-Modified Graphene for Flexible and High-Energy Ionogel-Based Microsupercapacitors.

Journal of the American Chemical Society, 2018
Scalable production of high-quality heteroatom-modified graphene is critical for microscale supercapacitors but remains a great challenge. Herein, we demonstrate a scalable, single-step electrochemical exfoliation of graphite into highly solution ...

Characterization of the chemical contents of fluorinated and fluorine-free firefighting foams using a novel workflow combining non-target screening and total fluorine analysis.

Environmental Science and Technology, 2019
Aqueous Film-Forming foams (AFFFs) are widely used to extinguish liquid fires due to their film-forming properties. AFFF formulation historically contains per- and polyfluoroalkyl substances (PFASs) that can be very persistent and pose a health risk to ...
