An ambient stable core-substituted perylene bisimide dianion: isolation and single crystal structure analysis

“…The enhanced thermodynamic stability of the PBI dianion in polar media sheds light on the formation and persistence of leuko bases in aqueous media which might also apply to other vat dyes such as BASF's famous indanthrene dyes and indigo. 4 , 21 …”

Comprehensive review of industrial wastewater treatment techniques

“…Wastewater from the dyeing and printing process is diverse because of the numerous dyes used and variations in the dyeing process. Dyes can be classified according to their chemical structure (such as azo, nitro, anthraquinone, cyanine, and carbonyl) or the type of fiber being dyed (cellulose, protein, and synthetic) and application (such as direct, acid, basic, cationic, direct, reactive, and mordant) (Correia et al 1994;Mustroph 2014). Synthetic dyes have been widely used for their color range, brightness of color, and fastness (Kant 2012).…”

Chemical constitutions in the Colour Index™: A century of colourant classification

“…10305; see Figure 8), which was discovered to dye silk yellow and shade Indigo dyeings green. 22,23 The Nitro class thus counts amongst its members one of the oldest kinds of synthetic dye. Use of the colourant did not gain traction with the craft; over 80 years would pass before the advent of synthetic dyes achieving significant commercial success (see Section 3.15).…”

“…23 Sufficient extension of the polymethine chain and judicious choice of terminal groups pushes absorption (and often emission) of light of wavelengths beyond the visible region, furnishing cyanine dyes that have been pivotal functional colourants in various technologies. 23 For example, they played a role in the evolution of optical disc data storage 50 and, as infrared sensitisers, have long served in silver halide photography, 51 while becoming greatly significant to computer-to-plate printing 52 and healthcare. 53 The relatively simple polymethine compounds that open the section are uncharged yellow disperse dyes made by condensing 4-dialkylaminobenzaldehydes with ethyl cyanoacetate, such as C.I.…”

“…The long obsolete method of destructive nitration of Indigo, first reported by Woulfe in 1771, 21 yields picric acid (C.I. 10305; see Figure 8), which was discovered to dye silk yellow and shade Indigo dyeings green 22,23 . The Nitro class thus counts amongst its members one of the oldest kinds of synthetic dye.…”
