Abstract

Thiophene-bridged triphenylamine dimers exhibit two-step near-infrared electrochromism with tunable absorptions extending deep into the NIR-III region. This simple yet powerful molecular design suggests a practical structural boundary for achieving reliable NIR-to-NIR optical switching, offering new insight into how π-extension and charge delocalization cooperatively govern long-wavelength responsiveness.
