| dc.description | 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 Â(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. | en-US |

Estos azo-polímeros mostraron una alta respuesta de ONL del tipo Â(3)a una excitación por debajo de la zona de absorción de los polímeros y sus valores de n2 fueron evaluados en el orden de 10⁻⁴ a 10⁻⁵ esu, con signo negativo para todos los materiales estudiados. | es-ES |
