抄録

A fluorescent dye anion (sulforhodamine B, SRB) was successfully introduced into a Fe(ii)-based metallo-supramolecular polymer (polyFe) by exchanging the counter anion. The exchange was confirmed by elemental analysis, UV-vis absorption spectroscopy, 1H-NMR spectroscopy, and FTIR spectroscopy. A solid-state device using the obtained polymer (polyFe-SRB) shows electrochromic properties based on the electrochemical redox of Fe(ii) ions by applying ±2.8 V. The device shows electrochemical switching of photoluminescence at 584 nm by applying ±2.8 V. This switching was caused by the appearance and disappearance of the metal-to-ligand charge transfer (MLCT) absorption of polyFe-SRB. It is considered that the MLCT absorbs the excitation light at 560 nm or the emission from SRB.
