“…Various types of fluorescent molecules can be introduced, as long as they can coexist with the metathesis catalyst used, and their structure does not interfere with the reaction activity of the monomer. For example, coumarin, 244 DABCYL, fluorescein, 208,236,245 EDANS, anthracene, rhodamine B, 207,208,244,[246][247][248] 7-chloro-4nitrobenzo-2-oxa-1,3-diazole (NBD), 244,249 Cy5.5, 250 Oregon Green, 251 indocyanine green, 195,[252][253][254] perylene diimide, 255 9,10-diphenylanthracene, 208 pyrene, 256 fluorene, 257 and nearinfrared (NIR) fluorescent cyanine, 258 can all be used. Lienkamp et al synthesised derivatives of oxanorbornenimide and 5-norbornene-2-carboxylic acid amide, modified with nitrobenzofurazan, coumarin, and rhodamine B 244 (Fig.…”
