✦ Synopsis

Candidate materials for electrochromic devices (e.g. viologens, conducting polymers, metallopolymers, metal oxides), generally exhibit redox states with distinctly different electronic UV/Vis absorption spectra. [1] Compounds that exhibit electrochromism in the near-infrared (NIR) region of the spectrum are much less well-known, despite the considerable technological importance of this region of the spectrum for uses as diverse as medicine (photodynamic therapy), telecommunications (silica-based fiber-optic devices operate in the 1300-1500 nm window), and even applications to aerospace and military camouflage. [2,3] Some conducting polymers have been shown to exhibit NIR electrochromism. [3] The wellknown reversible redox activity of transition metal complexes makes them excellent candidates for use as electrochromic materials, although this activity is usually confined to the visible region of the spectrum. [4] We recently described extensive series of both ruthenium-dioxolene and oxo-Mo v -[
