A sulfur analogue of a Pechmann dye has been synthesized. In addition to long-wavelength absorption and fluorescence, it showed multiple redox processes with low reduction potentials in cyclic voltammetry. The size effect of sulfur is responsible for its enhanced electron-accepting character.
Cyclisch und flexibel: Ein einfaches molekulares Design wird vorgeschlagen, mit dem sich die Molekülpackung und Festkörpereigenschaften π‐konjugierter Gerüste kontrollieren lassen. Feine Unterschiede in der Länge der flexiblen Alkylenbrücke cyclischer Terthiophendimere führen zu charakteristischen Molekülpackungen mit entsprechend spezifischen Festkörpereigenschaften, wie etwa Gelbildungsvermögen und photophysikalischen Eigenschaften.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
