Design and Synthesis of Red-Absorbing Fluoran Leuco Dyes Supported by Computational Screening [PDF]

open access: yesACS Omega
We report here on the design and synthesis of red-absorbing fluoran leuco dyes (LD). An essential part of the present dye development process is a computational screening of the candidate molecules, which allows for both time-efficient and accurate in silico characterization of the dyes.

Utilization of Tea Polyphenols as Color Developers in Reversible Thermochromic Dyes for Thermosensitive Color Change and Enhanced Functionality of Polyester Fabrics [PDF]

open access: yesMolecules
Thermochromic textiles possess the capability to indicate ambient temperature through color changes, enabling real-time temperature monitoring and providing temperature warnings for body heat management. In this study, three thermochromic dyes—blue, red,

Improvement of wet rub fastness in continuous dyeing with c.i. Sulphur Black 1 by ultrasonic treatment [PDF]

open access: yesUltrasonics Sonochemistry, 2023
C.I. Sulphur Black 1 is among the most important dyes for cellulose textiles, as this dye offers a maximum colour depth at reasonable costs. In its final form the dye is present as solid pigment, thus limited wet rub fastness can be an issue.

Spectrum Reconstruction Model Based on Multispectral Electrochromic Devices [PDF]

open access: yesAdvanced Science
Reconstructing the visible spectra of real objects is critical to the spectral camouflage from emerging spectral imaging. Electrochromic materials exhibit unique superiority for this goal due to their subtractive color‐mixing model and structural ...

The Effect of Temperature on Thermochromic Leuco Dyes: A Meta-Analysis

open access: yesJournal of Applied Agricultural Science and Technology
The effect of temperature treatment, either increasing or decreasing the temperature of leuco dyes, can produce thermochromic by looking at the changing color of samples resulting from experiments. The colors that are seen namely brightness (L), a* value,

Probing mechanism of Rhodamine B decolorization under homogeneous conditions via pH-controlled photocatalysis with anionic porphyrin [PDF]

open access: yesScientific Reports
Porphyrins are acknowledged for their efficacy as photosensitizers and show potential for the treatment of water contaminated with diverse dyes. This research emphasizes the use of meso-tetra(4-sulfonatophenyl)porphyrin (TPPS) as a photosensitizer for ...

Use of Leuco-Dyes in the Quantitative Colorimetric Microdetermination of Hemoglobin and Other Heme Compounds

open access: yesClinical Chemistry, 1975
Abstract Sensitivity, stability, and specificity of the color-producing reaction of hydrogen peroxide with benzidine, leucomalachite green, or o-dianisidine were tested in numerous systems containing hemoglobin and other hemoproteins.

Controlled Synthesis of Luminescent Xanthene Dyes and Use of Ionic Liquid in Thermochromic Reaction

open access: yesMolecules, 2022
In this study, we demonstrate six novel xanthene derivatives and their spectroscopic and chemical properties. The presented synthesis examination allowed us to obtain two different compounds during one step, with open and closed lactone rings substituted
