چکیده انگلیسی
Photo-responsive spiropyran-based compounds, such as, 1′,3′,3′-trimethyl-6-hydroxy-spiro(2H-1-benzopyran-2,2′-indoline) [OHSP], its monomer, such as 1′,3′,3′-trimethyl-6-methacryloyloxy-spiro(2H-1-benzopyran-2,2′-indoline) [MOSP] and its copolymers with methyl methacrylate [MMA] were synthesised using conventional synthetic routes. The copolymerisation was carried out either in tetrahydrofuran [THF] or in toluene using 2,2′-azobisisobutyronitrile [AIBN] as an initiator. The structures of these materials were investigated using 1H and 13C NMR spectroscopy. DEPT-135, HCCOSW and COSY45 NMR experiments were used to assign and interpret the complex structure of spiropyran based materials.
