poly(MMA-co-fluoresceinalkyl acrylates) were synthesized by the poly(MMA-co-chloroalkyl acrylates) and the dye, fluoresceinamine. First, we synthesized chloroalkyl acrylates, CH2=CHCOO(CH2)nCl ( n= 2,4,6,10 ) to control the spacer between a cladding and a dye. Second, monomers are copolymerized with methyl methacrylate(MMA). After poly(MMA-co-chloroalkyl acrylates) were synthesized, then attached the fluoresceinamine dye to the copolymer. At the end, we measured pH sensitive of them. On each step, we analyzed the molecular structure with FT-IR, NMR and the pH sensitive with UV-vis spectroscopy.
