Biodegradation of leuco derivatives of triphenylmethane dyes by Sphingomonas sp. CM9
Biodegradation, 2010A leuco derivatives of triphenylmethane dyes degrading bacterium, strain CM9, was isolated from an aquafarm field. Based on morphology, physiologic tests, 16S rDNA sequence, and phylogenetic characteristics, it was identified as Sphingomonas sp. This strain was capable of degrading leucomalachite green (LMG), leucocrystal violet and leucobasic fuchsin ...

Electrochemical control of luminescence color using luminescent leuco dye derivatives
Journal of the Society for Information Display, 2021AbstractElectrochemical switching of luminescence color, that is, electrofluorochromism, has received increasing attention because of its extensive applications. In this study, we investigate the combination of a luminescent EC molecule and a blue luminescent molecule to achieve electrochemical control of luminescence color by controlling the energy ...

Equilibrium Adsorption Values of Leuco Vat Dyes on Cotton
Journal of the Society of Dyers and Colourists, 1957The equilibrium adsorption of a series of leuco vat dyes on cotton has been measured in various concentrations of sodium chloride and sodium hydroxide. From the results the thermodynamic affinities have been calculated. Deviations from theory are observed in so far as the affinities are not constant, but show a regular drift as the concentration of ...

2002
The chemistry of quinone dyes has been discussed in a series of books entitled The Chemistry of Synthetic Dyes, edited by Venkataraman. The general chemistry of quinoid compounds has been discussed by Patai. There have been many books that cover quinoid compounds as dyes and pigments but very few discuss the chemistry of the corresponding leuco dyes ...

The analysis of indigoid dyes as leuco forms by NMR spectroscopy*
Coloration Technology, 20001H and 13C NMR spectra of halogen‐ and alkoxy‐substituted indigoid dyes (indigotins), and of some unknown deuterated indigotins as leuco forms (i.e., reduced forms or ‘vats’), in deuterium oxide are recorded and discussed. NMR spectroscopy is a useful technique for the identification and characterisation of this traditional class of vat dyes.

The Chemistry of Fluoran Leuco Dyes
2005In our information-oriented society, computer and facsimile are being widely used as a means for transmitting information. Carbonless copying papers and thermosensitive recording papers, which utilize a color-formation reaction between leuco dyes and acidic compounds, have won high regard as recording papers used with these office machines.

The Chemistry of Esters of Leuco Vat Dyes. V– The Action of Light
Journal of the Society of Dyers and Colourists, 1965The rates of reaction, under the influence of light, of the sulphuric acid esters of several leuco vat dyes have been measured in the presence of different amounts of hydrogen peroxide. The results can be explained if light causes hydrolysis of the sulphuric ester to the leuco vat dye, and it has been possible to demonstrate this reaction by ...
