Improving the nonlinear optical properties of organic materials through transition to macromolecular architectures of highly conjugated chromophores has been shown to be a viable strategy for generating materials suitable for TPA applications. In this study we display a simple and elegant method by which to synthesize macrocycles of porphyrin dimers. Two-photon absorption studies show 2 orders of magnitude enhancement of cross-section of the material, giving a maximum delta(2) of 10(6) GM.
通过向高度共轭发色团的大分子结构转变来改善有机材料的非线性光学性质,已被证明是生成适用于双光子吸收(TPA)应用材料的一种可行策略。在本研究中,我们展示了一种合成卟啉二聚体大环的简单而精巧的方法。双光子吸收研究表明,该材料的截面增强了两个数量级,最大δ(2)为10(6) GM。
