Abstract Electrochromic systems capable of switching absorption in the near‐infrared (NIR) region (750–2500 nm) are attractive from viewpoint applications for material and life science, thus several examples have been reported to date. In general, development organic‐based is needed reduce environmental impact improve biocompatibility. Although extending switchable spectral range crucial application organic electrochromic molecules, NIR based on redox interconversion still a challenging issue regarding reversibility durability during interconversion. To overcome this potential instability, introduction heteroatoms into molecular backbone and/or π‐extension could be useful strategies terms effective delocalization charge spin corresponding states. review, we focus redox‐active well‐defined small molecules that enable ON/OFF precise control states, present recent studies their intrinsic electrochemical spectroscopic properties structural characterization charged
