Tuning the wavelength of electrochemiluminescence by anodic potential: A design using non-Kekulé-structured iridium-ruthenium luminophores

摘要

Setting up spatially separated HOMO and LUMO regions in a non-Kekulé structured trinuclear Ir(iii)-Ru(ii)-Ir(iii) system and using oxidative-reduction electrochemiluminescence leads to emissions that are not detected in photoluminescence. Moreover, the new design allows tuning of the wavelength of emission in a stepless fashion as a function of the selected potential range.
