Cover Story: Electrochromic polymers are gaining importance in areas such as optical displays and switches, intelligent windows for architecture and room temperature control, etc., and, thanks to their flexibility, also in flexible electronics, robotics, camouflage textiles, etc. thanks to their flexibility. Here we introduce and characterize electrochromic properties of new metallo-supramolecular polymers (MSP) assembled from Fe(II) ions and unimers with thieno[3,2-b]thiophene-2,5-diyl central unit and different linkers connecting a,w-terpyridine end-groups. The color of these polymers ranges from blue-green to gray-green, red, and dark purple, depending on the linker. The highest contrast, fastest response, and topical coloration efficiency (641 cm2 C−1) showed Fe-MSP without linkers, while that with the longest linkers showed electrochromism in the NIR region.
