Plasmonic nanostructures provide unique structural coloration features via resonant interactions with light, rendering them useful in various optical applications. Here, new types of novel plasmonic-photonic Janus (PPJ) films are developed by introducing aluminum nanoislands on the surface of colloidal photonic crystal (CPC) arrays. Notably, the obtained PPJ films show vivid and tunable plasmonic colors ranging from purple to golden that can be regulated by the sizes of nanoisland architectures. Exquisite multicolored patterns on PPJ films have also been successfully achieved via regioselective deposition, showcasing enormous potentials in decorations. More intriguingly, by virtue of the sensitivity of Al nanoislands to the medium, the PPJ films display superior colorimetric detection ability in response to different solvents and biomolecule glucose. Leveraging these merits, advanced rewritable papers and reliable express waybills have been demonstrated based on PPJ films, offering abilities to deliver information reversibly and erase them on-demand. This work establishes a new platform for achieving versatile applications within a single plasmonic system, opening up vast possibilities for advancements in information delivery and personal information security.

Ink-free printing using photochromic paper has emerged as a promising technology for information recording, transmission, and secure interaction applications. Tungsten oxide quantum dots (WO 3 QDs), with their rapid UV response, excellent photochemical stability, and outstanding fatigue resistance, exhibit significant potential as an ink-free medium in the construction of sustainable rewritable paper. However, challenges such as low binding force, poor stability, and weak scalability limit the development of reversible photochromic paper based on WO 3 . In this study, a novel sustainable rewritable paper based on a scalable strategy of covalent modification and hydrophobic layer protection has been reported. Specifically, cellulose papers modified with silane coupling agent were directly grafted with amino-modified WO 3 QDs by covalent bonding through the addition reaction between epoxy and amine groups. Subsequently, the sustainable rewritable paper was obtained by the deposition of hydrophobic layer of polydimethylsiloxane (PDMS) via a dip-coating method. The rewritable paper exhibits exceptional properties, including high color contrast, extended color-retention (over 21 days), good rewritability (20 cycles) and excellent resistance to water or stains. Based on ink-free writing technology, the photo-responsive rewritable papers were utilized for anti-counterfeiting and encryption or decryption, demonstrating their great potential for information recording, storage, and security protection.

Photonic crystals film that possesses periodic dielectric structure have shown great prospect in developing environmentally friendly paper alternatives due to the unique properties of dye free and non-photobleaching, but their practical application is limited by the weak interaction between colloidal particles. Although some progress has been obtained, it is still a challenge to develop photonic paper with the desired mechanical and optical properties. Herein, multifunctional hard core/soft shell nanoparticles with controlled size are fabricated by semi-continuous seed emulsion polymerization method. Compared with convention colloidal particles, these core/shell nanoparticles can facile self-assemble into large-scale dense ordered structure film via dried at room temperature due to the relatively low glass transition temperature ( Tg ) of the shell layers. The facile fabrication route enables the continuous high-through put production of the photonic papers. The as-formed papers not only possess the capacity to solvent (water/ethanol) rewritable and multicolor painting, but also can rapidly reversible mechanochromic. Moreover, due to the good compatibility of core/shell interface, these photonic films possess excellent mechanical properties, demonstrating that this multifunctional film makes the fabrication of novel robust rewritable papers possible and enables visual monitoring of deformation degree.

To alleviate the negative effects of resource waste and environmental pollution caused by the excessive use of paper, technologies for rewritable paper have received widespread attention and in-depth research. Despite the growing interest in rewritable paper, meeting the requirements of large-scale preparation, long-lasting information storage time, high reversibility, and good environmental stability remains a huge challenge for this technology. This study developed a solvent-responsive copolymerized polyurethane-based rewritable paper with an inverse photonic glass structure (co-PUIPG paper). Comprehensive writing modes, including handwriting, spraying, and printing, were realized by using the swelling effect of different solvents and the local force field formed by capillary force to control the deformation degree of the inverse photonic glass structure. Co-PUIPG paper can persistently store high-resolution information and has a green and environmentally friendly “write–erase” method. Meanwhile, it exhibits good rewritability, as well as high mechanical strength and exceptional resistance to environmental factors, such as friction, high temperature, and sunlight. Because the spraying method can prepare templates quickly and extensively and polyurethane materials are economical, co-PUIPG rewritable paper possesses great potential as a substitute for commercial fiber paper and its industrialization is full of great possibilities.

Photoreversible color-switching materials, which can reversibly change color in response to external light stimuli, have attracted increasing attention for their applications in time-sensitive information storage and optical data storage fields. But most of the related materials are dyes or redox compounds with ultraviolet as the light source, dramatically limiting the cycling stability during discoloration processes. To address this problem, a near-infrared (NIR)-responsive rewritable paper via doping layered Co-metal–organic frameworks (MOFs) into the stable polyvinylidene fluoride matrix is reported for the first time. Layered Co-MOF shows a rapid color-switching characteristic between orange and black blue upon NIR illumination on/off because of the interlayer spacing changes. Benefiting from the soft network structures of the matrix, Co-MOF can be homogeneously distributed to deliver an outstanding reversibility performance, including rapid response, coloration in a short period, and decoloration within about 3 min in ambient air. The fabrication of new photoreversible color switching system holds great potential in communication security, which offers a viable pathway to achieve ink-free photoreversible printing.

As an information carrier, printing paper possesses a wide range of applications in many fields. However, its excessive waste, especially in the field of temporary reading, poses a threat to environmental resources and sustainable development. To alleviate this problem, photochromic materials that can be used for rewritable paper have aroused the interest of researchers. In this study, graphene quantum dots were creatively introduced into organic/inorganic hybrid system, promoting charge transfer induced by UV light and achieving rapid response characteristics. This novel material can achieve a maximum color contrast of 61.92% within 90 s and 86.8% of the maximum value in 10 s. In order to effectively avoid the failure of photoresponsive materials in contact with water, further spraying treatment endowed the material with superhydrophobicity and photoluminescence , forming a safe and stable system of information storage and transmission. Overall, this intelligent responsive material has broad application prospects in the field of anticounterfeiting rewritable paper.

Mechanochromic photonic crystals are attractive due to their force-dependent structural colors; however, showing unrecordable color and unsatisfied performances, which significantly limits their development and expansion toward advanced applications. Here, a thermal-responsive mechanochromic photonic crystal with a multicolor recordability-erasability was fabricated by combining non-close-packing mechanochromic photonic crystals and phase-change materials. Multicolor recordability is realized by pressing thermal-responsive mechanochromic photonic crystals to obtain target colors over the phase-change temperature followed by fixing the target colors and deformed configuration at room temperature. The stable recorded color can be erased and reconfigured by simply heating and similar color-recording procedures respectively due to the thermoswitchable on-off mechanochromism of thermal-responsive mechanochromic photonic crystals along with solid-gel phase transition. These thermal-responsive mechanochromic photonic crystals are ideal rewritable papers for ink-freely achieving multicolor patterns with high resolution, difficult for conventional photonic papers. This work offers a perspective for designing color-recordable/erasable and other stimulus-switchable materials with advanced applications.

The colour of water-jet rewritable paper (WJRP) is difficult to be expanded via single hydrochromic molecule, especially black. Here, inspired by the amazing phenomenon of bound-water in cells enabling various biological transformations via facilitating synergistic inter-/intra-molecular proton transfer, we present a simple strategy toward WJRP based on binary systems containing less-sensitive acidochromic dyes and mild proton donors (or developers). With such a binary system containing commercial black dye as the colouring agent, benzyl 4-hydroxybenzoate as the developer, and biomimetic bound-water as proton-transferring medium, we successfully achieve the long-awaited black WJRP. Printed images on such WJRP have excellent performances and long retaining time (>1 month). In addition, the robustness, durability and reversibility of WJRP could be increased distinctly by using polyethylene terephthalate as substrate. This strategy significantly expands hydrochromic colours to entire visible range in an eco-friendly way, which opens an avenue of smart materials for practical needs and industrialization.

Rewritable paper is of great significance for environmental and sustainable development. Specially, the water rewritable paper based on hydrochromism has aroused extensive research interesting for being clean, convenient and compatible with the current ink jet printer. Nevertheless, previously reported water rewritable paper requires complex and time-consuming fabricating process. Here, we report a facile strategy to fabricate structural colored water rewritable paper simply via two step infiltration on commercially available paper. After infiltration of graphene laminates and SiO 2 colloidal spheres in sequence, the obtained paper is integrated with assembled graphene laminates (AGLs)/amorphous colloidal arrays (ACAs) hierarchical composite structure. Owing to the advantageous micro-topography, selective separation capacity and high visible light absorption property of the underlying AGLs, SiO 2 ACAs with vivid structure color can be realized. Moreover, the hydrochomism of the hierarchical composite structure is resulted from the synergistic contribution of the hydrophilic structural color and the visible light absorption property of AGLs. Our strategy is based on the environmental-friendly structural color and convenient to realized, which offers a promising alternative to rapidly fabricate colored water rewritable paper.

Controlling the duration that information lasts on paper so that it disappears as desired is crucial for information security. However, this area is rarely studied. Here, we report [TEMA]2SbCl5 (1, TEMA+ = methyltriethylammonium), [TEA]2SbCl5 (2, TEA+ = tetraethylammonium), [TEBA]2SbCl5 (3, TEBA+ = benzyltriethylammonium), and [Ph4P]2SbCl5 (4, Ph4P+ = tetraphenylphosphonium) with structure-dependent reversible photoluminescent switching induced by the absorption and thermal release of small guest molecules including H2O, methanol, and ethylene glycol. Comparing the structural disorder levels, bond lengths, and luminescent Stokes shifts of the compounds aided in understanding their selective absorption behavior. Our results indicated that the information duration on the rewritable paper coated with the title compounds is easily tuned by changing the cation of the compounds, the type of guest molecules, and laser heating power. Our study opens previously unidentified avenues for information security and extends the potential applications of rewritable paper.

Environmentally friendly metal halides with reversible transformation of structure and luminescence properties have become a focal point of interest in the areas of anti-counterfeiting and sensors. Herein, Zn 2 + -doped DMAMnBr 3 and Mg 2+ -doped DMA 2 MnBr 4 were successfully synthesized using the evaporation-crystallization method. After doping Zn 2+ in DMAMnBr 3 , the photoluminescence quantum yield (PLQY) is enhanced from 18 % to 40 %. For DMAMnBr 3 , the introduction of Zn 2+ ions also accelerates the color-changing rate upon water absorption due to the tendency of Zn 2+ to form tetrahedral structures. Besides, the DMAMn 0.8 Zn 0.2 Br 3 exhibits excellent sensitivity. Hence, a temperature detection software is developed, which is capable of monitoring temperatures in the range of 323–403 K. For DMA 2 MnBr 4 , the incorporation of Mg 2+ ions not only leads to the enhancement of PLQY but also reduction of melting temperature. The theoretical calculation indicates that the decrease in the melting point is caused by the reduction in lattice energy. Utilizing this characteristic, we produced rewritable paper with excellent reusability. Finally, anti-counterfeiting labels were created using both DMAMn 0.8 Zn 0.2 Br 3 and DMA 2 Mn 0.95 Mg 0.05 Br 4 . The concealed information can be deciphered through straightforward heating. These results hold promise for extending the potential applications of manganese-based perovskite materials.

Over the past few decades, global paper consumption has continued to increase. The growing demand for paper has aggravated the negative impact on the environment. Therefore, the development of an erasable ink or rewritable paper seems to be an ideal way to alleviate this crisis. In this work, a hydrophilic anthracene derivative with nucleophilic substitution at position 9 was designed and synthesized. Such an anthracene derivative could disperse in aqueous solution and dimerize fast under irradiation of UV or visible light, accompanied by fluorescence quenching. Its aqueous solution could be used as a novel ink to be written on conventional paper, of which the handwriting was only visible under ultraviolet light. When exposed to sunlight, the handwriting would gradually disappear and not reappear after irradiating with ultraviolet light or heating. Therefore, it can be used as an erasable ink for applications in data confidentiality or paper reuse.
