Monodispersed nanospheres P(St/MAA) were synthesized by soap-free emulsion polymerization using styrene (St) and methacrylic acid (MAA) as the monomers, and ammonium persulfate (APS) as the initiator to construct photonic crystals (PCs). P(St/MAA) PCs were doped with carbon black (CB) modified by cationic surfactant cetyltrimethylammonium bromide (CTAB) to enhance color saturation. When CTAB concentration increased to 4.75 mmol/L, the arrangement of the nanospheres P(St/MAA) doped CB modified with CTAB (CTAB-CB) transitioned from long-range to short-range ordering because of the strong electrostatic attraction between negatively charged P(St/MAA) and positively charged CTAB-CB, and the resulted PCs became amorphous photonic crystals (APCs). Whereas, the APCs exhibited highly saturated structural color due to the suppression of incoherently scattered light by CB. The short-range ordering of APCs could eliminate angle dependence. In addition, micron mica were added as pearlescent fillers to prepare CTAB-CB-mica-P(St/MAA), which improved the lightness and adhesion of the APCs as pigments. The P(St/MAA) nanospheres with tunable particle sizes were obtained by regulating the monomer concentration in soap-free emulsion polymerization. These P(St/MAA) nanospheres as building blocks constructed the APCs pigments with controllable structural colors such as blue, cyan, green, and red. CB modified with CTAB, mica and P(St/MAA) were mixed in aqueous solution by sonication, centrifugation, then dried and ground, the APCs powders were obtained and could be applied directly as pigments without PCs assembly further. These highly saturated APCs pigments have potential applications in the field of cosmetics.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"235 ","pages":"Article 112646"},"PeriodicalIF":4.1,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we designed smart artificial skins that can produce extensive color by incorporating physical color and chemical colors together, similar to the integumentary structure of lizards. The mechanochromic hydrogel films embedded with colloidal crystals provide a dynamic structural color background, and the dyes entrapped in the hydrogels tune the composite color precisely. The composite color was computed by Grassmann's law and further quantitatively analyzed by the RGB and HSB color spaces. The computed results agree reasonably well with the experimental results. Thus, precise colors that are difficult to produce by only structural colors or dyes can be achieved by theoretical calculation. Furthermore, films with more realistic color are achieved by incorporating pH-responsive dye with tunable structural color, similar to the color-changing mechanism of lizards.

To overcome this deficiency, the functional group transformation (FGT) strategy was employed to convert the cyano group of one pyridine-2,6-dione derivative to a less electron-withdrawing amide group or even a hydrogen atom, so as to hinder the transformation from the hydrazone form to deprotonated azo form, and hence improve the acid-base stability of the target dyes. As a result, six new hydrazone dyes were synthesized with strong acid-base stability, which can be confirmed by related UV–Vis spectra. Reduced charge delocalization in the modified dyes, weakened molecular polarization, and increased energy barrier for the intramolecular transfer of the hydrazone proton were believed to play important roles in the fixation of hydrazone configuration for the new dyes. Detailed theoretical calculations further demonstrated the increased conversion energy barriers. The X-ray crystal structure analysis revealed that the decyano pyridine-2,6-dione dyes contain denser fused six-membered intramolecular hydrogen-bonding rings, and the hydrogen bond lengths are significantly shorter than those in previously reported pyridine-2,6-dione based dyes, which further stabilize the hydrazone protons of dyes in this work. The fundamental FGT strategy elucidated in this study is suggested to be helpful in the improvement of dyeing performance for a wide variety of existing hydrazone dyes.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"235 ","pages":"Article 112634"},"PeriodicalIF":4.1,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
