Recent Progress on Metallo-Supramolecular Polymers and the Electrochromic Devices Fabrication

抄録

This paper introduces our recent research on metallo-supramolecular polymers (MSPs) and the electrochromic (EC) device fabrication, including (1) control of metal sequence in one-dimensional (1D) MSPs, (2) design of two-dimensional (2D) MSPs, (3) three-dimensional (3D) hyperbranched MSPs, (4) EC devices (ECDs) with MSPs and (5) our trial for ECD applications. MSPs are a kind of coordination polymers and obtained by complexation of metal ions with multitopic organic ligands. MSPs show EC properties in the film state, activated by the electrochemical redox of the metal ions. The EC changes are caused by the reversible appearance and disappearance of the metal-to-ligand charge transfer (MLCT) absorption in the metal complex moieties of MSPs. ECDs with MSPs have great potential for the future’s smart window applications and spreading.
