Optically tunable nonlinearities in polymers based on photoisomerizable metal-based coordination complexes

The bottom-up design of polymer films exhibiting quadratic nonlinear optical properties that can be tuned optically and chemically is described. The polymer matrices are doped with metal-containing chromophores built around a Zn-II core and…

Anthryl-based poly(phenylene ethynylene)s: Tuning optical properties with Diels-Alder reactions

Soluble anthryl-based conjugated poly( phenylene ethynylene)s (PPEs) have been synthesized using palladium-catalyzed Sonogashira-Hagihara cross-coupling polymerization reactions. Molecular weights up to 3.5x10(4) g center dot mol(-1) were obtained,…

The effect of the conformation on the quadratic nonlinear optical response of metal carbonyl based chromophores with one-dimensional charge transfer capabilities: a computational investigation

The synthesis and the quadratic nonlinear optical (NLO) properties of (4-(4'-dimethylaminophenyl)pyridine)chromium and tungsten pentacarbonyl are reported. Experimentally, the chromophores exhibit molecular hyperpolarizabilities (beta) equal to 15.5…

Synthesis, characterization and nonlinear optical (NLO) properties of a push-pull bisboronate chromophore with a potential electric field induced NLO switch

A new bisboronate with five six-membered ring heterobicycles was prepared by reaction of [2-(2-hydroxy-4-diethylaminobenzylidene)amino]-5-nitroaminophenol and 1,4-phenyldiboronic acid, and its quadratic nonlinear optical (NLO) response was compared…

Analysis of the gelation process of hybrid silica-zirconia and silica-titania gels using two different grafted electroactive probes

Several conditions for the sol-gel polymerisation of hybrid silica-zirconia and silica-titania have been studied using specially tailored electrochemical probes. One of the probes has been designed to bind to the silica backbone, while the other has…
