Construction of coordination nanosheets (CONASHs) containing both inert and labile metal ions together is fundamentally significant but remains synthetically unachievable until now difficult to realize via conventional synthetic approach CONASHs due variable complexation conditions between heterometal organic ligands. Here, we demonstrate a strategy harness into structure by introducing the concept metalloligand. Metalloligands comprising ion (Os2+/Ru2+) free coordinating sites are designed synthesized can be further used as ligand bind (Fe2+) for building heterometallic (HMCONASHs). Following this, two HMCONASHs homoleptic complexes constructed that show broad absorption electrochemical window with reversible dual redox activity. Further, HMCONASH films exhibit multicolor electrochromism at different voltages, indicating their potential various applications. This may open create diverse structures functions hard achieve traditional approach.

Abstract Electrochromic (EC) technology is regarded as one of the most promising candidates for next‐generation reflective displays, owing to its advantages outstanding color adjustability, low energy consumption, vivid color, and flexibility, etc. However, current EC displays are seriously restricted by complicated expensive patterned methods. Herein, a facile low‐cost route developed achieve which fabricated based on combination an easily‐obtained material poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) efficient photo‐crosslinked additive (2,4‐hexadiyne‐1,6‐diol, HDDO). The micrometer‐scale patterns (<50 µm) can be achieved in situ process. As‐prepared devices show great performances containing fast response (<0.5 s), good reversibility (>10 000 cycles) high coloration efficiency (274.75 cm 2 C −1 ). More importantly, applications logo, QR code, price tag demonstrated successfully. Overall, exploration suggests efficient, low‐cost, method produce with performance, undoubtedly promote further development application displays.
