Abstract:
Abstract Carbonyl pigments are characterized by the presence of one or more carbonyl (C = O) groups in their structures, generally as a component of the chromophoric grouping and as part of an extended conjugated π-electron system. Structurally, they constitute a diverse group of pigments that offer a wide range of colors throughout the spectrum, and most of them provide high levels of technical performance. This paper provides a description of the historical development of thioindigoid, isoindoline, isoindolinone, and quinophthalone pigment types, and discusses their molecular and crystal str

Abstract:
The interaction of thioindigo and the phyllosilicate clay sepiolite is investigated using density functional theory (DFT) and molecular orbital theory (MO). The best fit to experimental UV/Vis spectra occurs when a single thioindigo molecule attaches via Van der Waals forces to a tetrahedrally coordinated cation with an additional nearby tetrahedrally coordinated also present. The thioindigo molecule distorts from its planar structure, a behavior consistent with a color change. Due to the weak interaction between thioindigo and sepiolite we conclude that the thioindigo molecule must be trapped

A novel thioindigo dye was synthesized, from 7, 7’-bis-chlorocarbonyl thioindigo, containing OH groups at the terminal positions of the oxyethylene side chains. The resultant dye 7, 7’-Bis[[2- [2-(2-hydroxyethoxy)ethoxy]ethoxycarbonyl]thioindigo (1) was characterized by 1H NMR, IR, and mass spectral studies. The thioindigo derivative (1), which possesses a molecular architecture, undergoes reversible photochromic reaction and capable of capturing different metal ions and transports them through liquid membrane.

Abstract:
The synthesis and comprehensive characterization of diamine and diimine derivatives of thioindigo are reported. X-ray crystal structures demonstrate a planar structure for the diimine derivatives and a twisted conformation for the diamines. The diamine compounds absorb in the UV (λmax 324 nm - 328 nm), and exhibit moderate fluorescence (ΦF = 0.25, 0.045). A transient triplet state is observed in laser flash photolysis (LFP) experiments, with lifetimes an order of magnitude longer than those of the triplet state of thioindigo. The diimine compounds absorb at longer wavelengths than the diam

A subsequent decrease of the voltage brought the system back to its initial state while demonstrating a significant hysteresis behavior.
