A viologen-based multifunctional Eu-MOF: photo/electro-modulated chromism and luminescence†
Abstract
A novel viologen-based multifunctional Eu-MOF was obtained by integrating a luminescent component Eu(NO3)3·6H2O and a viologen-functionalized ligand. The Eu-MOF not only exhibited reversible photochromic and electrochromic properties, but also displayed photoluminescent and electroluminochromic properties.
