- Non linear optical properties of novel amphiphilic azo-polymers bearing well defined oligo (ethylene glycol) spacers O.G. Morales-Saavedra T. García C. Caicedo E. Rivera Física, Astronomía y Matemáticas Polymers azobenzene optical properties poly(ethylene glycol) Non linear optical (NLO) properties of a new series of pnPEGMAN polymers: p2PEGMAN or Poly[(E)-2-(2-(methyl(4-((4-nitrophenyl) diazenyl)phenyl) amino)ethoxy)ethyl methacrylate], p3PEGMAN or Poly[(E)-2-(2-(2-(methyl(4-((4-nitrophenyl)diazenyl)phenyl) amino) ethoxy)ethoxy)ethyl methacrylate], p4PEGMAN or Poly[(E)-2-(4-((4-nitrophenyl)diazenyl)phenyl)-5,8,11-trioxa-2-azatridecan-13-yl methacrylate] and p6PEGMAN or Poly[(E)-2-(4-((4-nitrophenyl) diazenyl) phenyl) -5,8,11,14,17-pentaoxa -2-azanonadecan -19-yl methacrylate] were studied by the Z-Scan technique. These azo-polymers exhibited high χ(3) NLO-responses with excitation below the resonance absorption region of the polymers and the evaluated n2-values are in the order of 10-4 to 10-5 esu, with negative sign for all the studied materials. 2010 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57019194004 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
