Abstract
Electrochromic (EC) and electrofluorochromic (EFC) systems enable dynamic and reversible optical modulation via redox switching, yet conventional approaches face critical limitations: spatial patterning typically requires physical masks or electrode segmentation, and performance tuning relies on direct modification of chromophores or electrolytes. Here, we present a novel strategy that overcomes these constraints by creating spatially programmable crosslinking-density gradients within monolithic microarchitectures via digital micromirror device (DMD)-based maskless lithography. The locally modulated network density controls ion transport kinetics, thereby enabling position-dependent redox switching without altering the chromophore chemistry. Upon voltage application, hidden high-resolution patterns—including fine-art reproductions—are reversibly revealed through dual-mode optical responses. This platform opens new avenues for advanced optical devices and secure information encoding.
