Light-induced second-harmonic generation in azo-dye polymers.
TL;DR: The permanent all-optical poling of an azo-aromatic acrylic copolymer is experimentally demonstrated by seeding preparation in a backward phase-conjugation geometry by monitoring the characteristic kinetics of monitored by second-harmonic generation.

Quasi-permanent all-optical encoding of noncentrosymmetry in azo-dye polymers
TL;DR: In this article, an original poling technique that uses a purely optical excitation process is presented, which consists of a seeding-type process that alternates between writing and probing periods.

TL;DR: A simple analytical model shows that the successive resonant lengths differ by a multiple of one-half of the wavelength of the supported short-range surface plasmon polariton.

Surface-Induced Chirality in a Self-Assembled Monolayer of Discotic Liquid Crystal
Fabrice Charra,J. Cousty +1 more
TL;DR: In this article, the emergence of chirality through self-assembly into monolayers of non-chiral discotic liquid crystals, hexakis-2,3,6,7,10,11-alkyloxytriphenylene, on the nonchiral surface of highly oriented pyrolitic graphite was observed.

Synthetic strategies to derivatizable triphenylamines displaying high two-photon absorption.
Rémy Lartia,Clémence Allain,Guillaume Bordeau,Falk Schmidt,Céline Fiorini-Debuisschert,Fabrice Charra,Marie-Paule Teulade-Fichou +6 more
TL;DR: The good optical properties of the new derivatizable pi-conjugated TPA combined with their small size and their compatibility with bioconjugation protocols suggest that they represent a new chemical class of labels potentially applicable for the tracking of biomolecules using two-photon scanning microscopy.
