In our research endeavors, we have synthesized a series of metallo-supramolecular polymers with organometallic bonds, specifically PolyRuRu, PolyRuFe, and PolyRuZn. Notably, PolyRuZn exhibited absorption within the NIR region at around 1100 nm with high contrast ratio (ΔT > 60%), impressive color efficiency (η = 333 cm2/C), within the NIR spectrum.
