Electrochemically Controllable Emission And Coloration By Using Europium(Ra) Complex And Viologen Derivativesf

摘要

We have demonstrated electroswitchable emission and coloration using a novel composite material containing luminescent europium(m) complex Eu(hfa)3(H2O)2 and diheptyl viologen HV2+. The photoluminescence of the Eu(iu) complex was controlled by the electrochemical coloration of HV2+ via intermolecular energy transfer mechanisms
