摘要：

A new low-bandgap conjugated polymer is synthesized (see Figure for structure). It is transparent, easily processed, and exhibits electrochromic behavior specific to the near-infrared region of the spectrum. The absence of electrochromic behavior in the visible range may permit this polymer to be used in near-infrared device applications.
