Synthesizing 2D metal-organic frameworks (2D MOFs) in high yields and rational tailoring of the properties in a predictable manner for specific applications is extremely challenging. Now, a series of porphyrin-based 2D lanthanide MOFs (Ln-TCPP, Ln=Ce, Sm, Eu, Tb, Yb, TCPP=tetrakis(4-carboxyphenyl) porphyrin) with different thickness were successfully prepared in a household microwave oven. The as-prepared 2D Ln-TCPP nanosheets showed thickness-dependent photocatalytic performances towards photooxidation of 1,5-dihydroxynaphthalene (1,5-DHN) to synthesize juglone. Particularly, the Yb-TCPP displayed outstanding photodynamic activity to generate O2 - and 1 O2 . This work not only provides fundamental insights into structure designing and property tailoring of 2D MOFs nanosheets, but also pave a new way to improve the photocatalytic performance.

可控合成基于卟啉的二维镧系金属有机骨架，具有依赖于厚度和金属节点的光催化性能。

以高产量合成2D金属有机框架（2D MOF），并以可预测的方式针对特定应用合理地调整性能是非常具有挑战性的。现在，在家用微波炉中成功制备了一系列不同厚度的基于卟啉的二维镧系元素MOF（Ln-TCPP，Ln = Ce，Sm，Eu，Tb，Yb，TCPP =四（4-羧基苯基）卟啉）。制备的2D Ln-TCPP纳米片表现出厚度依赖性的光催化性能，对1,5-二羟基萘（1,5-DHN）的光氧化反应可合成胡桃木。特别地，Yb-TCPP显示出优异的光动力活性以产生O 2-和1 O 2。这项工作不仅为2D MOF纳米片的结构设计和性能定制提供了基本见识，而且还为改善光催化性能铺平了道路。
