A Relaxation Study of Poled Nonlinear Optical Polymers by Infrared Reflection-Absorption Spectroscopy
The relaxation of poled nonlinear optical (NLO) chromophores in polymer films was characterized by infrared reflection-absorption spectroscopy. Both a guest-host system and a photocrosslinkable polymer system were investigated. Polymethylmethacrylate (PMMA) doped with either 2-methyl-4- nitroaniline...

| description | The relaxation of poled nonlinear optical (NLO) chromophores in polymer films was characterized by infrared reflection-absorption spectroscopy. Both a guest-host system and a photocrosslinkable polymer system were investigated. Polymethylmethacrylate (PMMA) doped with either 2-methyl-4- nitroaniline (MNA) or 4(4'-nitrophenylazo) phenylamine (DO3) was studied. The photocrosslinkable polymer system, polyvinylcinnamate (PVCN) doped with 3- cinnamoyloxy-4-4-(N,N-diethylamino)-2-cinnamoyloxy phenyl azo nitrobenzene (CNNB-R) was also investigated. Doped NLO active molecules were aligned using the corona poling technique. Infrared spectra as a function of time were used to monitor the relaxation behavior of the oriented dyes after poling. Relaxation of NLO molecules was followed at various characteristic vibrational frequencies. The relaxation of MNA was found to be faster than that of DO3. The NLO dye molecule, CNNB-R was covalently bonded to the host polymer and formed a three dimensional crosslinked network after ultraviolet (UV) irradiation. Relaxation of NLO molecules in pristine and UV treated samples were compared. UV light induced crosslinking provided better temporal stability of molecular alignment in this system...
