  具有大的双光子吸收截面的扩展方酸染料

  摘要：

  扩展的双（供体）取代的方酸根发色团在近红外区域表现出非常高的双光子截面（高达 33 000 GM）；这些可归因于大跃迁偶极子与小失谐能量的组合。已发现对于这些发色团之一，在 1.3 mm 处的三阶非线性光学磁化率的模量为 7.0 x 10-11 esu。

  In various embodiments, chromophores are described that include novel electron acceptors, novel electron donors, and/or novel conjugated bridges that are useful in nonlinear optical applications. In some embodiments, the present invention provides chromophore architectures wherein a chromophore contains more than one electron acceptor in electronic communication with a single electron donor, and/or more than one electron donor in electronic communication with a single electron acceptor. Also described is processes for providing materials comprising the novel chromophores and polymer matrices containing the novel chromophores. Electro-optic devices described herein contain one or more of the described electron acceptors, electron donors, conjugated bridges, or chromophores.

  Extended bis(donor)-substituted squaraine chromophores exhibit very high two-photon cross-sections (as high as 33 000 GM) in the near-IR; these can be attributed to the combination of large transition dipoles with small detuning energies. The modulus of the third-order nonlinear optical susceptibility at 1.3 mum has been found to be 7.0 x 10-11 esu for one of these chromophores.
