Synthesis and Photophysical Properties of New Pyrazolino[60]fullerenes with Fluorenyl and Fluorinated Phenyl Substituents. -The photophysical properties of the compounds are investigated. Their weak emission indicates fluorescence quenching induced by intramolecular charge transfer that might occur between the donor and acceptor parts of the system. -(ZHANG*, J.; SHEN, S.; HE, S.; CHENG, H.; XU, C.; DENG, H.; Heterocycles 89 (2014) 4, 971-980, http://dx.
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.
