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,…

Structural and Photoisomerization Cross Studies of Polar Photochromic Monomeric Glasses Forming Surface Relief Gratings

A novel class of photochromic materials based on polar azo derivatives containing functionalized biphenyl substituents has been synthesized. Once melt and cooled, these compounds formed amorphous transparent monomeric materials whose glass…

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…

Large quadratic nonlinear optical efficiencies in pseudosymmetric streptocyanine dyes

The quadratic (proportional to E-2) nonlinear optical (NLO) properties of pseudosymmetric organic cations are investigated. These chromophores belong to a family of highly polarizable streptocyanine dyes built in two steps by amination of their…

Synthesis of Novel Rod-Shaped and Star-Shaped Fluorescent Phosphane Oxides - Nonlinear Optical Properties and Photophysical Properties

The design of a new class of fluorophores is presented. Some push–pull chromophores (D–π–A) containing polyphenylethynyl units and a phosphane oxide moiety were efficiently prepared from common intermediates. Straightforward syntheses gave novel one…
