Selective electrochromic (EC) switching in the wide range from visible (VIS) to near-infrared (NIR) wavelengths was achieved using triple-redox-active metallosupramolecular polymers (MSPs), synthesized by 1:1 complexation of a transition metal salt and bisterpyridine ligand containing tetraphenylbenzidine (TPB) moiety. By tuning an oxidation potential between 0 1.2 V vs Ag/Ag+, MSPs (polyFeLTPB polyRuLTPB) were capable selective reversible triple-band EC modulation (400–750 nm), NIR-I (750–1000 NIR-II (1000–1600 nm) regions. Interestingly, exhibited excellent properties with remarkably high optical contrast (98%), coloration efficiency (CE) (851 cm2/C), fast switching, even NIR region. A made-to-order quasi-semigel state device exceptionally long cycle stability (>7000 cycles) region at incredibly low operational voltage (1.2 V). These two ECDs demonstrated that significant amount solar irradiance (about 33–36%) shielding band 750–1670 nm while allowing 46–53% VIS transparency under voltage. At dark mode 0.8 V, they exhibit 59–63% 45–47% blocking.
