Electrochromic materials using mechanically interlocked molecules

摘要: Recent investigations on the design and synthesis of electrochromic materials based switchable three-station [2]catenanes are summarized. The reasoning preliminary experiments behind electrochemically controllable red–green–blue (RGB), donor–acceptor presented. A basis for color generation is discussed in which tetracationic cyclophane, cyclobis(paraquat-p-phenylene), serves as π-electron deficient ring circumrotates between three rich recognition sites within a macrocyclic polyether, generating different colors (RGB) charge transfer interactions cyclophane 1,5-dioxynaphthalene (R), tetrathiafulvalene (G) benzidine (B). Issues relating to realization an RGB [2]catenane raised discussed: they include (i) tuning, (ii) thermodynamic considerations, (iii) electrochemistry model compounds, (iv) molecular design, (v) electrochemical behavior (vi) electrochromism polymer gel matrices. Finally, challenges that need be met future if ideal catenane prepared, outlined.
