Journal ArticleDOI
Large Quadratic Hyperpolarizabilities with Donor–Acceptor Polyenes Exhibiting Optimum Bond Length Alternation: Correlation Between Structure and Hyperpolarizability
Mireille Blanchard-Desce,Valérie Alain,Peter V. Bedworth,Seth R. Marder,Alain Fort,Claude Runser,Marguerite Barzoukas,Sonja Lebus,Rüdiger Wortmann +8 more
TL;DR: In this article, the reduction of the bond length alternation (BLA) in the polyenic chain has been investigated, and unprecedented quadratic hyperpolarizabilities (p) have been achieved (up to p(0) =I500 x 10-30esu) by reduction.
Journal ArticleDOI
Deviations from Kleinman symmetry of the second-order polarizability tensor in molecules with low-lying perpendicular electronic bands
TL;DR: In this article, the second-order polarizability tensor of 4.4-Nitroaniline (pNA) and 3.5-dinitro-anilines (3,5-DNA) were studied by electric field induced second harmonic generation (EFISH) and electrooptical absorption measurements (EOAM) in dioxane solution at T = 298 K.
Journal ArticleDOI
Intramolecular charge transfer in elongated donor-acceptor conjugated polyenes
Mireille Blanchard-Desce,Mireille Blanchard-Desce,Rüdiger Wortmann,Sonja Lebus,Jean-Marie Lehn,Peter Krämer +5 more
TL;DR: In this paper, the authors investigated the effect of the length of the polyenic chain linking the donor and acceptor end groups of donor-acceptor polyenes on the ICT absorption band.
Journal ArticleDOI
Electrooptical absorption measurements of phototautomerizing systems: S0 and S1 static polarizabilities of bipyridinediols
TL;DR: The ground-state polarizability tensor is anisotropic, the main component lying in the long molecular axis as mentioned in this paper, and nuclear contributions to the static polarization were found to be small (5-10%).
Journal ArticleDOI
Elongated push–pull diphenylpolyenes for nonlinear optics: molecular engineering of quadratic and cubic optical nonlinearities via tuning of intramolecular charge transfer
Valérie Alain,Stéphane Rédoglia,Mireille Blanchard-Desce,Sonja Lebus,Katarzyna Lukaszuk,Rüdiger Wortmann,Ulrich Gubler,Christian Bosshard,Peter Günter +8 more
TL;DR: In this paper, a series of soluble push-pull diphenyl polyenes of increasing length and having various donor (D) and acceptor (A) end groups have been synthesized and investigated.
