A Multifunctional Dysprosium‐Carboxylato 2D Metall–Organic Framework

We report the microwave assisted synthesis of a bidimensional (2D) MOF of formula [Dy(MeCOO)(PhCOO)2]n (1) and its magnetically diluted analogue [La0.9Dy0.1(MeCOO)(PhCOO)2] (1 d). 1 is a 2D material with single‐ion‐magnet (SIM) behaviour and 1 d is a multifunctional, magnetic and luminescent 2D mate...

Summary:We report the microwave assisted synthesis of a bidimensional (2D) MOF of formula [Dy(MeCOO)(PhCOO)2]n (1) and its magnetically diluted analogue [La0.9Dy0.1(MeCOO)(PhCOO)2] (1 d). 1 is a 2D material with single‐ion‐magnet (SIM) behaviour and 1 d is a multifunctional, magnetic and luminescent 2D material. 1 can be exfoliated into stable nanosheets by sonication. Microwave assisted synthesis is applied to prepare a dysprosium 2D‐MOF with simple carboxylato ligands, [Dy(MeCOO)(PhCOO)2]n (1). The Dy(3+) ions are arranged into nanosheets in a hexagonal pattern, stacked by van der Waals forces similar to those of graphene. The magnetically diluted MOF 1 d is a bifunctional 2D luminescent material with SIM properties.
