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 ...

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 ...

A tight binding model of the bond dissociation mechanism in thermochromic leuco dyes
Journal of Molecular Structure, 2020Abstract It has long been known that heat, UV light, or protonization will cause the bond in Leuco dye's to break. The underlying microscopic mechanism is a still a matter of discussion. It stands to reason that a local model should correctly predict the temperature behavior of the heat capacity at the thermochromic phase transition.

The Chemistry of Esters of Leuco Vat Dyes. V– The Action of Light
Coloration Technology, 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 ...

Experimental Work: Thermochromic Leuco Dyes
2020Development of paste recipes with TC and conventional pigments for textile printing is commonly realized through empirical processes. Towards a systematic and more accurate process to create TC textiles, this chapter presents experimental work based on instrumental processes of paste recipe formulation and respective integration in textile substrates ...

Radiochromic leuco dye micelle hydrogels: II. Low diffusion rate leuco crystal violet gel
Physics in Medicine and Biology, 2009Radiation-sensitive hydrogels offer the capability of verifying intricate dose distributions in three-dimensional (3D) space conveniently in a single measurement with sub-millimetre spatial resolution. In this study, a new radiochromic hydrogel called leuco crystal violet (LCV) micelle gel is introduced. Upon irradiation, LCV converts to crystal violet
