“…During the dyeing process, CMC is the feasible target in the first dye diffusion step. 80 Deep eutectic solvents have a good ability to combine with proteins via H bonds and can also exert a potential effect on the lipid structure. [81][82][83][84] When a fresh acidic deep eutectic solvent is used in the dyeing process, the dye dissolved in the solvent is transferred to the fabric surface, and the H bond between the deep eutectic solvent and the CMC layer loosens the scale layer, which accelerates the dye diffusion speed.…”

“…85,86 The H bond can counteract the electrostatic repulsion between the dye and the fiber and increase dye aggregation, leading to an increase in dye concentration on the wool surface layer and consequently causing an increase in diffusion gradient to the interior of the woolen fabric. 80 An increase in temperature increases the average speed of molecules in the liquid, which decreases the average intermolecular forces and consequently reduces fluid resistance (to flow) or 'viscosity' (shown in Table 6). 87,88 In this study, the dyeing of woolen samples was performed in a rapid lab-scale oscillating dyeing machine with a liquid-to-fabric ratio of 20 : 1, which ensured total soaking of the fabric in the dye bath, and the dye bath was constantly stirred.…”

“…10-The activity (acidity) of the 2-hydrogen atom in the quaternary salts of benzothiazole, benzoxazole, benzoselenazole and/or benzoimidazole is related to the presence of the highly electron attracting positive charge on the quaternary nitrogen atom at position 3 of these compounds in addition to the electron pulling characters of the hetero atom present and the electron attracting character of the condensed benzene ring system (Scheme 16). Cyanine dyes also might have enhanced biological properties, which need to be tested evaluated (Abate et al, 2019;Ayare et al, 2019;Karcı et al, 2013;Manjunatha et al, 2019;Mishra et al, 2019;Negm et al, 2016;Rizk et al, 2015;Rizk et al, 2017;Sadeghi-Kiakhani et al, 2019;Şener et al, 2018;Silva et al, 2018;Sun et al, 2019;Zhang et al, 2019).…”

In this paper, synthesis of different classes of five/six membered heterocyclic cyanine dyes has been reviewed. In this paper review detailed synthesis steps were represented via equations. The synthesis covers, monomethine cyanine dyes (simple cyanine dyes), dimethine cyanine dyes, trimethine cyanine dyes (carbocyanine dyes), styryl cyanine dyes (hemicyanine dyes), aza-styryl cyanine dyes (aza-hemicyanine dyes and/or aza-cyanine dyes), merocyanine dyes (acyclic merocyanine dyes and cyclic merocyanine dyes) and apocyanine dyes. Besides, in the introduction section of this review paper some light is focused on the uses, applications and properties of cyanine dyes. This review paper is informative, useful and very readable for synthetic dye chemists, researchers and students who look for the different methods in the synthesis and preparation of various classes of five/six membered heterocyclic cyanine dyes with special emphasize in the field of heterocyclic and/or cyanine dyes chemistry. This specific type of collective review in the synthesis of different classes of only five/six membered heterocyclic cyanine dyes has been paid little attention and has great importance in the chemistry literature.

“…Acid dyestuffs are a structurally simple but important dye category mainly used for dyeing wool, silk and nylon fabrics under acidic conditions 1–6 . The main binding force between the acid dye and fibre is the ionic bond which is easily dissociated by water ionisation, resulting in low wet fastness 7,8 .…”

The importance of quinonoidal planarity in improving the wet fastness of acid dyes was studied in a new series of N‐sulphonatoalkyl‐substituted indophenine derivatives. These derivatives were synthesised via the sulphonatoalkylation reaction of isatins with alkanesultone or sodium bromoalkanesulphonate followed by the indophenine reaction. The effects of the position of sulphonic acid groups, length of the alkyl chain, and electron‐donating/withdrawing groups on geometry, electronic structure, solubility, and absorption properties were systematically examined and correlated with the performances of the dyes on wool, silk and nylon fabrics. The N‐sulphonatoalkyl indophenine dyes could exhibit a blue colour in N,N‐dimethylformamide (DMF) and on silk or nylon fabric but a purplish colour in water and on wool fabric. Methoxy groups had a negative impact on the molar extinction coefficient and dye exhaustion, leading to relatively poor dyeing performance. In comparison, fluorine or chlorine atoms were less influential. The introduction of nitro groups could induce a yellowness to the dyed fabrics caused by the strengthened absorption at the region of 360 to 420 nm and reduce the dyeing rate and wet fastness level due to the low dye–fibre affinity. In general, the N‐sulphonatoalkyl indophenine dyes exhibited satisfactory washing and rubbing fastness, especially on dyed nylon fabric. This study provides insight into the structure–property relationship of indophenine dyes and demonstrates that sulphonatoalkylation is an efficient methodology for designing high‐performance textile dyestuffs based on quinonoidal heterocyclic structures.
