New highly electrodeficient cationic fluorescent tetrazines: a step toward the strongest purely organic photooxidants

Fluorescent strongly electrodeficient tetrazines substituted with cationic heterocycles have been prepared. These compounds can be reversibly reduced at a high potential and consequently their excited state is a strong oxidant. As a result of their…

Efficient Sensing of Explosives by Using Fluorescent Nonporous Films of Oligophenyleneethynylene Derivatives Thanks to Optimal Structure Orientation and Exciton Migration

The fluorescence of thin films of a diimine-substituted phenyleneethynylene compound can be efficiently quenched by nitroaromatic vapors, which is not the case for the unsubstituted parent compound. Thin-film porosity is usually considered to be an…
