Abstract

Red emissive dyes with xanthene core have been developed (D1-5) and were characterized using NMR and HRMS spectral analysis. The prepared dyes showed absorption in solution and solid states at the red region. The photoaging studies were performed to measure the stability of the prepared dyes. The photoaging effect of these dyes was verified exceptionally by exposing them to a very strong beam of UV light. The fluorophore D1 showed better stability, with minimal intensity loss of less than 5 % in absorbance and fluorescence methods. Thermal stability was assessed using TGA, DSC, and XRD measurements. Further, the dyes were formulated for ink application and used to paint in different substrates. The substrates were subjected to photoaging tests under UV light, and their color strength was measured with a data color tool and surface morphology using SEM analysis. FT-IR spectroscopy was used to confirm the surface changes during UV light radiation.

红发染料的稳定性、光老化研究及其在各种承印物上的油墨适用性

研制了含杂蒽核的红色荧光染料（D1-5），并对其进行了NMR和HRMS表征。所制备的染料在红色区域表现出固溶吸收。通过光老化实验来测定所制备染料的稳定性。这些染料的光老化效应是通过将它们暴露在非常强的紫外光束下得到验证的。荧光团D1表现出较好的稳定性，在吸光度和荧光方法中强度损失小于5%。热稳定性通过TGA， DSC和XRD测量进行评估。此外，染料被配制为油墨应用，并用于在不同的基材上绘画。基材在紫外光下进行光老化测试，用数据显色工具测量其颜色强度，用SEM分析表面形貌。利用傅里叶变换红外光谱分析了紫外光照射下的表面变化。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
