Novel profluorescent mono- and bis-​isoindoline nitroxides linked to naphthalimide and perylene diimide structural cores are described. These nitroxide-​fluorophore probes display strongly suppressed fluorescence in comparison to their corresponding non-​radical diamagnetic methoxyamine derivs. The perylene-​based probe possessing two isoindoline systems tethered through ethynyl linkages was shown to be the most photostable in soln., demonstrating significantly enhanced longevity over the 9,​10-​bis(phenylethynyl)​anthracene fluorophore used in previous profluorescent nitroxide probes.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
