Synthesis and nonlinear optical properties of linear and Λ-shaped pyranone-based chromophores
摘要:
New, pyranone-based chromophores were synthesized and their (nonlinear) optical properties were measured. The chromophores were prepared by first condensing an electron withdrawing group with pyranone, followed by reaction with an aldehyde-functionalized pi-conjugated bridged donor molecule. This approach enables one to easily incorporate the pyranone moiety and to prepare both linear and A-shaped chromophores. The (nonlinear) optical properties were measured using femtosecond hyper-Rayleigh scattering. These measurements demonstrated the advantages of this approach. (c) 2008 Elsevier Ltd.

Dipolar, V-shaped compounds derived from 4H-pyranylidene-linked acceptors have been synthesized, and their linear and nonlinear optical properties (displaying mu beta values up to 3000 x 10(-48) esu) have been compared to those of analogous one-dimensional derivatives. The pyranylidene ring behaves strictly as a spacer, and not as a donor group. (C) 2009 Elsevier Ltd. All rights reserved.

New non-linear cross-conjugatedpolyenes containing a central 4-ylidene-substituted pyran or N-methyldihydropyridine ring have been synthesized. Interaction of chromophores in these compounds occurs through the ylidene group linked to the heterocycles.
