Description
This study focused on the synthesis and evaluation of novel photo-stable profluorescent nitroxide probes. The stability and performance of the newly synthesised probes were assessed under harsh environmental environments and compared with previously synthesised PFN probes. Analysis of their physical characteristics revealed that the nitroxide-fluorophore probes displayed strongly suppressed fluorescence in comparison to their corresponding non-radical derivatives. Evaluation of these probes confirmed their enhanced ability to detect radical polymer degradation in the laboratory and in true weathering conditions over any previously synthesized profluorescent nitroxides or other laboratory techniques.
Impact and interest:
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.
Full-text downloads:
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
