Photoresponse of new azo pyridine functionalized poly(2-hydroxyethyl methacrylate-co-methyl methacrylate)

The study aimed to synthesize of azopyridine functionalizated poly(2-hydroxyethyl methacrylate-co-methylmethacrylate) (azo(HEMA-co-MMA), characterization of azopolymer including thermal and photoisomerization studies, and generate diffraction and surface relief gratings (SRG).

The data includes:

• ¹H NMR, TGA, DSC for new azo(HEMA-co-MMA) and polymer matrix p(HEMA-co-MMA)
• WAXD for azo(HEMA-co-MMA)
• FTIR for azo(HEMA-co-MMA)
• Calibration curve in NMP for 4-(4-hydroxyphenylazo)pyridine
• UV-Vis spectra for azo(HEMA-co-MMA) in NMP solution (c = 10-5 mol/l)
• Cis-trans isomerization for azo(HEMA-co-MMA) in solid state. Trans-cis reaction was generated by 365 nm diode light.
