“…They were rather low indicating that they were oligomers. It is consistent with literature data for similar materials [50][51][52][53]. During synthesis, the high content of the initator was used (10% by weight towards monomers).…”

In this work, a novel photoresponsive materials has been successfully developed. We have synthesized the series of azopolymers containing derivatives of sulfamerazine and studied their photochromic properties. The polymers were obtained from methacrylate azomonomers, butyl methacrylate and isobornyl methacrylate by radical polymerization. Spectral properties and photoisomerization kinetic constants were determined for thin transparent films, using UV-Vis spectroscopy. The maximum absorption of the films was observed at 432-440 nm. The obtained materials showed ability to reversible trans-cis photoisomerization. Reversibility of the process was confirmed during ellipsometric measurements. The change of the real part of the complex refractive index induced by laser irradiation was between 0.010 and 0.053. Additionally, some properties of described polymers and azobenzene derivatives were calculated and were utilized in order to better understand the differences in the photochromic behaviour of the new materials. Moreover, we determined the suitability of the obtained azopolymers for spontaneous surface relief grating inscription.Spontaneous surface relief grating recording on the thin azopolymer films was carried out using set-up with one laser beam. The spontaneous SRG was successfully recorded in all investigated polymers.

“…The monomer M6AzCOONa was prepared by alkalized process of 6-[4-(4-carboxylphenylazo)phenoxyl]hexyl methacrylate (M6AzCOOH), which was synthesized according to published references [45,46]. Typically, M6AzCOOH (4.1 g, 0.01 mol) was dissolved in THF (50 mL) using 5 wt% NaOH aqueous solution to adjust to pH ¼ 9.…”

“…MAzoA-0 was synthesized according to a literature procedure. 37 The desired azo monomers with an easily cross-linkable substituent (MAzoS-n, n ¼ 0, 2, 6, 10) were then readily prepared through the coupling reaction between MAzoA-n and N-hydroxysuccinimide, using DCC as the catalyst. All the intermediates and azo monomers could be obtained in quite good yields, typically ranging from 55% to almost quantitative yields, and their purity was satisfactory, as determined with both thin layer chromatography and 1 H NMR.…”
