Conventional polymers of nonfluorescent monomers show strong
fluorescence without incorporating any fluorescent agent. The intensity
of photoluminescence of these polymers is similar to that emitted by
conventional fluorophore-containing polymers. This finding offers a
simple yet versatile platform to prepare polymers of strong fluorescence
without using fluorescent molecules.
For details, they observed that the non fluorescent monomer forming a
fluorescent polymer without incorporating any fluorophore, is not
specifi c to NIPAM/PNIPAM. When other nonfluorescent
vinyl monomers (e.g., methyl acrylate (MA), N,N –dimethylacrylamide
(DMA) and styrene (St)) were subjected to the RAFT polymerization
mediated by trithiocarbonate RAFT initiator.
Those findings are pretty similar to what we have observed for our
UV-initiated polymerization. I can see green fluorescence when polymers
