“…The current quinoline‐derived tricyanofuranhydrazone‐based probe can be reported a simple and efficient colorimetric chemosensor for the detection of copper ions in aqueous media, and under various pH values. As compared to previous detection tools, which typically require complicated electronic components, trained workers and sophisticated operations [39–41] . the current colorimetric paper strip is distinguished by simplicity, portability, real‐time, and flexibility for onsite detection of copper in aqueous media with a detection limit of 50–300 ppm.…”

Metallochromic Hydrazone‐Based Chemosensor with Application in a Colorimetric Paper Strip for Selective Detection of Cu²⁺

A new tricyanofuranhydrazone‐based colorimetric chemosensor (TCFH) was synthesized and immobilized onto paper strips for selective detection of Cu2+ in aqueous environments. The synthesis strategy of TCFH involved an azo‐coupling process between the diazonium salt of 8‐aminoquinoline and an active methyl‐bearing tricyanofuran (TCF) heterocyclic moiety. Due to intramolecular charge transfer, TCFH chromophore demonstrated pronounced solvatochromism depending on the solvent polarity. Changes in both color and UV‐Vis absorption spectra demonstrated by the developed chemosensor proved that TCFH can be utilized to detect Cu2+ in the presence of other competing metallic cations and anions. The synthesized TCFH probe, which contains a hydrazone recognition moiety, demonstrates dramatic solvatochromic activity and high selectivity at the microlevel of copper ions with a color shift from yellow to purple. Moreover, test strips of TCFH were successfully developed and applied for the detection of copper ions at different concentrations in aqueous media. The colorimetric properties of the prepared TCFH‐immobilized paper strips were investigated by CIE Lab chromogenic parameters, colorimetric strength (K/S) and UV‐Vis absorbance spectra. The best detection of Cu2+ was achieved in the pH range of 6.6–7.4 demonstrating an immediate color switch relying on the total content of Cu2+. SEM was applied to characterize the deposition of tricyanofuranhydrazone onto the surface of the paper strip.

Temperature-driven colorful switching inks have been an interesting security encoding method to improve the anticounterfeiting properties of commercially available merchandise. Recently, thermochromic inks have faced many disadvantages, such as low efficiency, high cost, and low durability. In the current study, we developed self-healable ink from poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPSA) integrated with the anthocyanidin(ACY)-based red-cabbage extract in the presence of ferrous sulfate for authentication purposes. Self-healable inks have been able to guarantee durability and thermal stability. Environmentally friendly, ACY-based chromophore was extracted from Brassica oleracea L. var. Capitata (red-cabbage) to serve as a spectroscopic probe immobilized into PAMPSA. The prepared self-healable nanocomposite ink (PAMPSA-ACY) displayed temperature-induced chromism with high reversibility and thermal stability. Different self-healable nanocomposite inks of thermochromic features were prepared employing different ratios of the ACY-based red-cabbage extract. As described by Commission Internationale de L’éclairage Lab coordinates, homogeneous films were stamped on the paper surface to show a purple color (631 nm) able to switch color into red (458 nm) with the increase in temperature from 25 to 65 °C, respectively. Transmission electron microscopy, infrared spectra (FT-IR), energy-dispersive X-ray, and scanning electron microscopy were utilized to inspect the morphological behavior and chemical compositions of thermochromic prints. Both mechanical and rheological properties of ink-printed paper substrates and ink solution were also investigated. Both of antimicrobial activity and cytotoxicity study of the nanocomposite ink (PAMPSA-ACY) were also evaluated. Various industries can take the advantage of the current ink as a competent approach for anticounterfeiting purposes.

Preparation of novel authentication film by screen printing of anthocyanin biomolecular extract: Thermochromism and vapochromism

et al. 2023

View full text Add to dashboard Cite

Novel thermochromic and vapochromic paper substrates were prepared via screen printing with anthocyanin extract in the presence of ferrous sulfate mordant, resulting in multi‐stimuli responsive colorimetric paper sheets. Environmentally friendly anthocyanin extract was obtained from red‐cabbage (Brassica oleracea var. capitata L.) to function as spectroscopic probe in coordination with ferrous sulfate mordant. Pink anthocyanin/resin nanocomposite films immobilized onto paper surface were developed by well‐dispersion of anthocyanin extract as a colorimetric probe in a binding agent without agglomeration. As demonstrated by CIE colorimetric studies, the pink (λmax = 418 nm) film deposited onto paper surface turns greenish‐yellow (λmax = 552 nm) upon heating from 25 to 75°C, demonstrating new thermochromic film for anti‐counterfeiting applications. The thermochromic effects were investigated at different concentrations of the anthocyanin extract. Upon exposure to ammonia gas, the color of the anthocyanin‐printed sheets changes rapidly from pink to greenish‐yellow, and then immediately returns to pink after taking the gaseous ammonia stimulus away, demonstrating vapochromic effect. The current sensor strip showed a detection limit for ammonia gas in the range 50–300 ppm. Both thermochromism and vapochromism showed high reversibility without fatigue. In addition to studying the rheological properties of the prepared composites, the morphological and mechanical properties of the printed cellulose substrates were also studied.
