An electrochromic system offering ease of color tunability was constructed using a triple‐decker Pt II complex. The divalent complex shows electrochemically quasi‐reversible two‐electron transfer coupled with the coordination/dissociation of axial ligands forming higher valent Pt(+2.67) species. This complex exhibits characteristic colors from red to purple, blue, and cyan depending on coexisting halide ions. The triple‐decker structure provides a novel multicolor electrochromic system with favorable stability and reversibility. More information can be found in the Full Paper by M. Yoshida, M. Kato et al. on page 7669.
