Polymethine Dye Synthesis and Its Leuco Property Investigation

Molecular Crystals and Liquid Crystals, 2007
Polymethine dyes have been synthesized using bis-dimethylaminophenylethylene compound. These dyes can be converted to the colorless leuco form by the treatment with alkali. Interestingly, these leuco dyes showed reversible color formation properties with following acid addition.

Aromatic aldehyde-leuco dye photoxidation

Pure and Applied Chemistry, 1977
Tris (dimethylaminophenyl) methane leuco dyes undergo rapid photoxidation together with aromatic aldehydes. Quantum yields for dye formation in film media are ~750. A practical photoimaging system based on this chemistry was developed. The chemical aspects of sensitization, achievement of dark stability, and the rendering of the films photo-insensitive

Radiochromic leuco dye micelle hydrogels: I. Initial investigation

Physics in Medicine and Biology, 2009
This investigation reports the use of surfactants and colorless leuco triarylmethane dyes to form a new class of radiochromic micelle hydrogels for three-dimensional (3D) water-equivalent dosimetry. Gelatin gel samples with several surfactants and leuco dyes were prepared and evaluated for optical transparency, dose sensitivity and diffusion rates. The

Radiochromic leuco dye micelle hydrogels: II. Low diffusion rate leuco crystal violet gel

Physics in Medicine and Biology, 2009
Radiation-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
