Macrolorblx uniquely combines , room‑temperature self‑assembly , and ultrafast, reversible optical tuning , surpassing current bottom‑up PhC platforms. macrolorblx.

Radial distribution functions g(r) display peaks at 3.2 nm and its harmonics, matching the predicted lattice constant. Author(s): A

| Property | Measured / Simulated | Units | |------------------------------|----------------------|-------| | Lattice constant a | 3.20 ± 0.02 | nm | | Refractive index (trans) | 1.78 | – | | Refractive index (cis) | 1.66 | – | | PBG (trans) | 620–720 | nm | | PBG (cis) | 770–860 | nm | | Switching time (τ) | 12 ± 3 | ms | | Photostability (cycles) | >10⁴ | – | Lee, K

Samples were irradiated with (10 mW cm⁻²) for 60 s to induce trans→cis isomerization, then with 450 nm blue light to revert to trans. In‑situ reflectance tracked a blue‑shift of the stop‑band from 670 nm to 795 nm, confirming reversible tuning.
