Preparation of oriented thin films of a series of soluble conjugated polymers and characterization of linear and nonlinear optical properties is described and discussed. The orientation of polymer chains leads to an enhanced cubic susceptibility, imp

Two-photon absorbing chromophores were designed and investigated for optical power limitation based on multiphoton absorption processes. These molecules combine very large two-photon absorption cross-sections (with typical σ 2p maximum values of 3

Linear and nonlinear optical properties of thin films of pure fumrot, and mono -, as well as di - substituted with nitro group, rotaxanes were studied by m-lines spectroscopy and by third harmonic generation techniques, respectively. The molecules fo

The influence of charge injection induced by an electric field on the optical absorption of -sexithiophene () thin films is studied. The analysis of this electro-modulated absorption (EMA) at variable incidence angle and wavelength enables us to dete

We report on the influence of field-effect charge injection on optical absorption and fluorescence properties of α -sexithiophene ( α -6T) thin films. We have performed electromodulated absorption (EMA) and electromodulated fluorescence (EMF) measu

Optically nonlinear disperse red 1 (DR1) was covalently bound into a silica gel network by the coupling of DR1 and 3-isocyanatopropyltriethoxysilane. Organic-inorganic hybrid materials present a large resonant second-order susceptibility (d33 = 55 pm

Second order nonlinear optical properties of poled thin films of a guest–host system consisting in a charge transfer chromophore dissolved in poly bis(phenol A carbonate) matrix were studied by optical second harmonic generation and as function of

In this paper we describe the synthesis of a new class of high glass transition temperature polyurethanes functionalized with two quasi 1D charge transfer dyes. The polymers are soluble in several organic solvents and can be processed into thin films

A competitive approach to obtain functionalized polymers is described in this presentation. It consists on the use functionalized sol–gel systems, known to form excellent optical quality thin films. Usually these systems suffer of the low density o
