The integration of anionic TiL (L = embonate) cages and π-conjugated coordination cations into ordered structures can produce high-performance nonlinear optical (NLO) materials. More specifically, by employing TiL cages for assembly with mixed ,-chelated and ,-chelated type conjugated organic ligands and Ag ions, three cage-based structures have been synthesized and structurally characterized. Among them, an ion pair structure with strong π-π accumulation exhibits a significant third-order NLO response, and an excellent optical limiting effect has been experimentally verified. This work provides a promising material for NLO applications.
将阴离子型TiL（L = 恩波酸盐）笼与π共轭配位阳离子整合到有序结构中可制备出高性能非线性光学（NLO）材料。更具体地说，通过使用TiL笼与混合的、α-螯合和β-螯合型共轭有机配体以及Ag离子进行组装，已合成并对三种基于笼的结构进行了结构表征。其中，具有强π-π堆积的离子对结构表现出显著的三阶NLO响应，并且通过实验验证了其优异的光限幅效应。这项工作为NLO应用提供了一种有前景的材料。
