Abstract

Abstract: 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. Abstract : Durch dick und dünn : Eine Serie Porphyrin‐basierter 2D‐Lanthanoid‐MOFs unterschiedlicher Dicke wurde über eine Mikrowellen‐assistierte Route hergestellt. Die photokatalytische Aktivität der erhaltenen Nanoblättchen lässt sich effektiv durch die Dicke und die Metallknotenpunkte regulieren.
