A viologen-based multifunctional Eu-MOF: photo/electro-modulated chromism and luminescence.

Chem Commun (Camb)

Green Catalysis Center and College of Chemistry, Zhengzhou University, Zhengzhou 450001, China.

Published: November 2020

A novel viologen-based multifunctional Eu-MOF was obtained by integrating a luminescent component Eu(NO)·6HO and a viologen-functionalized ligand. The Eu-MOF not only exhibited reversible photochromic and electrochromic properties, but also displayed photoluminescent and electroluminochromic properties.
