Four imidazole type chromophores bearing diamino groups were designed and synthesized with a facile method. All the chromophores possess efficient second-order nonlinearities based on MOPAC/AM1 calculation, high thermal stability and good transparency for the application in NLO materials. Chromophore 1d, an X-type dual charge transfer system, shows well-balanced nonlinearity/transparency properties.

AbstractInitial results of a project directed towards the design and synthesis of ferroelectric liquid crystal polymers (FLCPs) for second order nonlinear optics (NLO) applications are described. FLCP glasses represent a novel type of solid, a truly noncrystalline solid with thermodynamically stable polar order. FLCPs with useful magnitude of the second order susceptibility χ(2) and processability not possible with poled polymers or crystals have been obtained.

AbstractA high -μβ chromophore APII utilizing isophorone as π-conjugation bridge was processed into both PMMA guest host and crosslinked (XL) polyurethane network with various loading densities. High electro -optic coefficients, r33 = 30 pm/V (in PMMA) and r33 = 32 pm/V (in polyurethane) at 1.06 μm were obtained. Alignment temporal stability ranged from 90 to 120°C for XL polymer network. There is virtually no intrinsic absorption loss at 1.3 μm (solution measurement). Also noteworthy is that high optimum loading densities of this chromophore are attainable in both cases without detectable chromophore aggregation due to intermolecular electrostatic interactions.

AbstractThe rocketed development concerning electro-optic polymers fundamentally motivated by its pragmatic application in envisioning second-order nonlinear optics and waveguiding are cardinal. Modern synthetic strategies consigned an outstanding optical quality amorphous polymers with enhanced properties. Documented data revealed a huge progress in understanding their implementation, however challenges still exist regarding their temporal stabilities etc. This review delivers a brief investigation of nonlinear optical (NLO) polymer materials demonstrated over previous decades. Besides, their categorical explanation along with their structural architecting via engineering polymeric backbone or functionalization of the molecular entities have been reviewed. Correspondingly, their temporal and thermal stabilities accompanied by NLO characteristics features are also discussed.
