在紫红色、靛蓝等染料的发现和商业化之后，工业界早就知道的染料和颜料化学的概念经历了一次彻底的修正。除了作为着色剂的传统作用外，有机染料和颜料已被确定为高端技术应用（包括光学和电子设备）不可或缺的来源。随着p共轭体系的超分子化学的进步和有机半导体材料的分化发展，一些染料和颜料已经成为当代光电器件的潜在候选者。在所有的主要颜料中，二酮吡咯（DPP），也被称为“法拉利颜料”及其衍生物，已经成为一类主要的有机功能染料，在工业颜料、有机太阳能电池、有机场效应晶体管和生物成像等领域得到了广泛的应用。自1974年Farnum和Mehta发现dpp衍生染料以来，dpp衍生染料因其诱人的颜色、合成可行性、易于功能化和可调的光学和电子性质而迅速受到关注。基于dpp的小分子和具有定向形态和电子特征的低聚物的超分子聚合的进展导致了高性能光电器件的发展。在这篇综述中，我们重点介绍了DPP衍生物在光电应用方面的最新进展，这些衍生物专门用于形成超分子聚合物。(C) 2020 Elsevier Ltd.版权所有。
The very concept of dye and pigment chemistry that was long known to the industrial world underwent a radical revision after the discovery and commercialization of dyes such as mauveine, indigo, and so on. Apart from their conventional role as coloring agents, organic dyes, and pigments have been identified as indispensable sources for high-end technological applications including optical and electronic devices. Simultaneous with the advancement in the supramolecular chemistry of p-conjugated systems and the divergent evolution of organic semiconductor materials, several dyes, and pigments have emerged as potential candidates for contemporary optoelectronic devices. Of all the major pigments, diketopyrrolopyrrole (DPP) better known as the `Ferrari Pigment' and its derivatives have emerged as a major class of organic functional dyes that find varied applications in fields such as industrial pigments, organic solar cells, organic field-effect transistors, and in bioimaging. Since its discovery in 1974 by Farnum and Mehta, DPP-derived dyes gained rapid attention because of its attractive color, synthetic feasibility, ease of functionalization, and tunable optical and electronic properties. The advancement in supramolecular polymerization of DPP-based small molecules and oligomers with directed morphological and electronic features have led to the development of high performing optoelectronic devices. In this review, we highlight the recent developments in the optoelectronic applications of DPP derivatives specifically engineered to form supramolecular polymers. (C) 2020 Elsevier Ltd.
