摘要
通过液相外延层层自组装的方法,用乙酸锌和5,10,15,20-四(4-吡啶基)卟啉钴为原料,成功制备了具有[010]取向的二维吡啶卟啉基MOFs(ZnTPyP(Co))薄膜。通过Z-扫描技术研究了该薄膜的光限幅行为,并探究了卟啉环中心螯合金属钴离子对薄膜的光限幅性能的影响。卟啉环中心钴离子的引入可以增强卟啉基团中电子的离域性,从而提高其光限幅性能。这些发现为光限幅应用提供了新的候选材料,也为拓展MOFs薄膜材料在激光防护领域的应用奠定了基础。
Two-dimensional pyridylporphyrin-based MOF(ZnTPyP(Co))thin film with[010]-orientation growth from zinc acetate and 5,10,15,20-tetrakis(4-pyridyl)-porphyrin(Co)ligand was obtained by using a liquid-phaseepitaxial(LPE)layer-by-layer(lbl)growth approach.The optical limiting(OL)behavior of ZnTPyP(Co)thin film was evaluated by Z-scan technique.In addition to,the effect of the coordinating Co ions within the porphyrinic core on OL performance was investigated.The introduction of the Co ions in the porphyrinic core could enhance the delocalization of electrons in porphyrinic group,resulting in improving the OL performance.These findings provide new candidates material for the OL application and lay a foundation for expanding the application of MOF thin films in the field of laser protection.
