| 摘 要： | 选取易于制备的MOFs（ZJU-28）为功能性载体，将具有非线性光学性质的2种阳离子染料DB和TM与载体孔道中的二甲胺阳离子进行交换，实现阳离子型有机荧光离子在金属有机框架中定向组装，获得具有非线性光学效应的复合材料。强极性染料离子DB和TM在晶体孔道中的定向排布，改变了原有MOFs晶体的中心对称性。通过共聚焦显微镜观察到，原来不具有非线性光学效应的ZJU-28晶体通过有机阳离子交换后，形成的DB@ZJU-28和TM@ZJU-28复合材料具有较强的倍频效应和双光子荧光。

| Abstract: | Novel composites with nonlinear optical effect were prepared by exchanging the dimethylamine cation with DB and TM in MOFs (ZJU-28) channels. DB or TM cations with strong polar were arranged along one direction in crystal pores, leading to non-central symmetric crystal. Compared to original ZJU-28, the composite crystals, DB@ZJU-28 and TM@ZJU-28, possess strong second harmonic generation (SHG) and two-photon absorption fluorescence observed through confocal microscopy. |

| Keywords: | metal organic framework ZJU-28 host-guest interactions second-harmonic generation two-photon excitation fluorescence |
