Optical multiplexing technologies, which integrate multiple optical channels based on photonic structures, offer a significant solution for high-capacity information storage and advanced encryption. However, these materials are limited by their inherent unswitchable chiral result in restricted control over the spatial distribution of light. Here, we propose to construct an integrating optical-multiplexed structure using tunable 1D crystals orientation texture via combined self-assembly shear-aligning approach. In this system, created diverse ethyl cellulose (EC) offers wide range light modulations through phase retardation. When with chromatic layer formed EC, wavelength polarization achieved. Notably, due identical components modulation crystal layers, traceless interface between them ensures both high confidentiality durability. By leveraging hierarchical slices well-defined states structural colors created, enabling construction platform multiplexed multichannel 3D 4D This study presents promising strategy develop traceless, highly confidential units controllable color encryption technologies.

The photoluminescent naphthalimide moiety bonded β-CD entrapped in the cavity. Its fluorescence highly weakened cavity recovers after being expelled from competing guest molecule emit bright green photoluminescence under UV. Experiments theoretical calculations suggest π-π stacking ICT primary mechanism naphthalimides assembly fluorescence, which can be quenched through insertion of conjugated molecules recover removing insert.

This has great importance energy conservation purposes. Military and civilian emergency thermochromic applications require rapid visible-light stealth (VLS); however, concurrent transmission VLS is yet be realized. Inspired by squid-skin, we propose micropatterned hydrogel (MTH) realize control of transmittance at all-working temperatures. The MTH possesses two optical regulation mechanisms: property scattering, controlled pressure, respectively. introduced surface micropattern strategy can arbitrarily switch between normal diffuse time within 1 s compared with previous ~180 s. also high solar-transmission range 61%.
