Abstract:4,5-Dimethoxy-2-nitrobenzyloxycarbonyl group acting as a photolabile protecting group was bonded on 3-aminopropyl silica gels through a covalent bond in a 46% yield. The deprotection was performed under UV-irradiation. The resulting amino group was analyzed through the use of a confocal laser-scanning microscope using 4-(10,15,20-triphenylporphyrinyl)phenyl fluorophore.
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.
