“…Reactive dyes, one kind of important organic dyes, are mainly used for dyeing and printing natural fabrics [18]. These dye molecules contain water-soluble groups (usually sodium sulfonate), and have good water solubility [19], but the dye molecules still tend to aggregate by self-association of the hydrophobic π-π conjugated parts of the molecular structure [20][21][22][23][24], which will lead to the formation of dimers, trimers [25], etc.…”

The aggregation structure of dye molecules has a great influence on the properties of dye solutions, especially in high concentration. Here, the dye molecular aggregation structures were investigated systemically in aqueous solutions with high concentration using three reactive dyes (O-13, R-24:1 and R-218). O-13 showed stronger aggregation than R-24:1 and R-218. This is because of the small non-conjugate side chain and its β-linked position on the naphthalene of O-13. Compared with R-218, R-24:1 showed relatively weaker aggregation due to the good solution of R-24:1. The change of different aggregate distributions in the solutions were also investigated by splitting the absorption curves. Moreover, it is found that the surface tension of solutions can be modified by the combined effect of both aggregation and the position of the hydrophilic group, which, however, also have an effect on viscosity. This exploration will provide guidance for the study of high concentration solutions.

“…1 Azo dyes are formed through the diazotization reaction process, in the presence of nitrous acid (HNO 2 ), at 0 to 5 0 C temperature. 2,3 Azo dyes are commonly used as coloring agents in diverse industries such as plastic, 1, 4 textile, 5 printing, 6,7 and paper industry 8 . Various literature reports illustrate wide range of metal sensor which can sense metals through different mechanisms viz colorimetery, fluorescence, aggregation-induced emission (AIE), [9][10][11] and aggregation-induced emission enhancement (AIEE), 12-14 via metal to ligand charge transfer, 15 or ligand to metal charge transfer, 16 photoinduced electron transfer (PET), [17][18][19] donor-acceptor processes, [20][21][22] .…”

In this manuscript, we report for the very first time synthesis of a new purple azo dye (E)-1-((5-methoxy thiazolo[4,5-b]pyridin-2-yl) diazenyl) naphthalen-2-ol (TPN1). TPN1 also exhibits very interesting sensing behavior and can be potentially used for highly selective and sensitive detection of Cu2+, Sn2+ and Al3+. The changes in the absorption properties of TPN1 in the presence of various cations were studied extensively by UV visible spectroscopy. TPN1 dye which exhibits purple color changes to blue, orange, and lavender color respectively on addition of Cu2+, Sn2+, and Al3+ ions respectively. Notably, TPN1 reveal different color with the number of metal ions but the peak shifting could be observed only with three metal ions in solution. Addition of Cu2+ to TPN1 caused bathochromic shift, while in the case of Sn2+ and Al3+ a hypsochromic effect could be observed through UV-visible spectroscopy.

“…Although these phase change microcapsules endow the wall coating with heat storage properties, most of them have a single color, which is difficult to meet the aesthetic needs of modern people. Organic reactive dyes are the main colorants used in the dyeing of cotton fabrics, which have excellent sunlight and weather resistance and can be used in the field of building walls [ 31 , 32 , 33 ]. For example, Lei et al [ 34 ] studied the effect of utilizing colored cooling paint and PCMs as an auxiliary cooling strategy in reducing the cooling load of tropical buildings through experiments and numerical researches.…”

This article reports the design and manufacture of colored microcapsules with specific functions and their application in architectural interior wall coating. Utilizing reactive dyes grafted SiO2 shell to encapsulate paraffin through interfacial polymerization and chemical grafting methods, this experiment successfully synthesized paraffin@SiO2 colored microcapsules. The observations of surface morphology demonstrated that the colored microcapsules had a regular spherical morphology and a well-defined core-shell structure. The analysis of XRD and FT-IR confirmed the presence of amorphous SiO2 shell and the grafting reactive dyes, and the paraffin possessed high crystallinity. Compared with pristine paraffin, the thermal conductivity of paraffin@SiO2 colored microcapsules was significantly enhanced. The results of DSC revealed that the paraffin@SiO2 colored microcapsules performed high encapsulation efficiency and desirable latent heat storage capability. Besides, the examinations of UV-vis and TGA showed that the paraffin@SiO2 colored microcapsules exhibited good thermal reliability, thermal stability, and UV protection property. The analysis of infrared imaging indicated that the prepared latex paint exhibited remarkable temperature-regulated property. Compared with normal interior wall coatings, the temperature was reduced by about 2.5 °C. With such incomparable features, the paraffin@SiO2 colored microcapsules not only appeared well in their solar thermal energy storage and temperature-regulated property, but also make the colored latex paint coating have superb colored fixing capabilities.
