Abstract

Common organic small molecule dyes exhibit chemical modifiability and are easy to polymerize, making them potential monomers in organic electronics. The multifunctionality of organic synthetic chemistry allows for material adaptability. Here, we report the synthesis route and purification methods for dye polymer based on thiophene-diketopyrrolopyrrole. Their orderly conjugated structure and high coplanarity contribute to a high crystallinity, which is favorable for charge carrier transport. By adjusting the device structure and thin film preparation conditions, the hole transport properties of the materials were further optimized, achieving a maximum mobility of up to 0.35 cm² V⁻¹ s⁻¹. The excellent charge carrier performance reveals the potential of such material for applications in organic electronics.

具有高平面特征的 PNDT-T-DPP 染料基聚合物的光物理和电化学特性表征及有机电子应用开发

常见的有机小分子染料具有化学可改性，易于聚合，因此是有机电子学的潜在单体。有机合成化学的多功能性使材料具有适应性。在此，我们报告了基于噻吩-二酮吡咯的染料聚合物的合成路线和纯化方法。它们的有序共轭结构和高共面性有助于获得高结晶度，从而有利于电荷载流子的传输。通过调整器件结构和薄膜制备条件，进一步优化了材料的空穴传输特性，使其最大迁移率达到 0.35 cm2 V-1 s-1。优异的电荷载流子性能揭示了这种材料在有机电子学中的应用潜力。

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.
