Nonlinear Optical Polymer

This study uses the inclusion complex method to import nonlinear optical (NLO) chromophores, disperse red1 (DR1), and spiropyran (SP), into theγ-CD cavity of theγ-cyclodextrin polymer (γ-CDP) to prepare orderly aligned nonphotocontrollable and photocontrollable nonlinear optical polymers. Calculations support the ultraviolet/visible analyses and suggest the formation of the 1 : 2 DR1/γ-CDP and 1 : 2 SP/γ-CDP inclusion complexes. Upon complexation, the DR1 and SP molecules are free to align themselves along an applied electric field and show high order parameters of approximately 0.48 and 0.20, respectively. Reversible photochromic reactions exhibit that the SP/γ-CDP complex still retains the photochromic properties following corona poling.

ABSTRACTPhotoconductivity measurements on an epoxy-based photocrosslinkable second-order nonlinear optical (NLO) polymer - DGENC - NAC ( diglycidyl ether of nitrocatechol / nitroaniline prepolymer functionalized with cinnamoyl groups) are presented. Without introducing any sensitizer or charge carrier transport agents, large photoconductivity was obtained in this polymer system. Optical excitation of the NLO chromophores leads to photocarrier generation and it is conjectured that these NLO chromophores also play a role in the carrier transport. This polymer is one of the candidate materials for photorefraction.

ABSTRACTThe photobleaching mechanism of nonlinear optical polymers has been investigated; the PMMA based polymers with nonlinear optical chromophores, 4-dimethylamino-4'-nitro-stilbene (DANS), 4-dimethylamino-4'-hexylsulfone-stilbene (DASS), and 4'-(2-hexyloxyethyl) ethyl amino-4-nitro azobenzene (DR-16). The photobleaching was carried out using near-UV lines. FTIR spectra and UV-VIS absorption spectra were obtained after each photobleaching. Refractive indices were measured in the photobleaching processes. The results suggest that the photobleaching mechanism of two PMMA based side-chain polymers with DANS and DASS chromophores results from the photo-oxidation and that of the PMMA based host-guest polymer with DR-16 chromophore results from the combination of the photo-degradation and the trans-cis conformational transformation.
