Diketopyrrolopyrrole (DPP)-Based Materials and Its Applications: A Review

Abstract

Diketopyrrolopyrrole (DPP) and its derivatives have been widely studied in the past few years due to its intrinsic physical and chemical properties, such as strong electron-withdrawing, deep color, high charge carrier mobility, strong aggregation, good thermal-/photo-stability. In the 1970s, DPP was developed and used only in inks, paints, and plastics. Later, DPP containing materials were found to have potential other applications, typically in electronic devices, which attracted the attention of scientists. In this feature article, the synthesis pathway of DPP-based materials and their applications in organic field-effect transistors, photovoltaic devices, sensors, two photo-absorption materials, and others are reviewed, and possible future applications are discussed. The review outlines a theoretical scaffold for the development of conjugated DPP-based materials, which have multiple potential applications.

Benzo/Naphthodifuranone‐Based Polymers: Effect of Perpendicular‐Extended Main Chain π‐Conjugation on Organic Field‐Effect Transistor Performances

“…[ 1–4 ] A great material library of new CPs have been established, which together with surface engineering of the device interfacial layers and optimization of device fabrication procedures, have led to significant improvements of device performances in many electronic applications such as organic thin‐film transistors (OFETs), organic solar cells (OSCs), and so on. [ 5–10 ] Among tremendous efforts to elevate their device performances, the material design of new CPs with novel molecular structures and ideal physicochemical properties serves as the cornerstone for the success of the organic electronic areas. [ 11–14 ] Specifically, the backbone structures of CPs, not only has a crucial effect on the intramolecular π‐orbital overlap and delocalization, but also play an important role for enhancing the inter‐(macro)molecular interactions via π–π stacking.…”

Diketopyrrolopyrrole Based Organic Semiconductor Materials for Field-Effect Transistors

“…The core endowed the DPP derivatives with strong electron deficiency properties, which can be used to build donor-acceptor system molecules. In addition, once the aromatic groups were flanked with small units, the conjugated backbone of the DPP exhibited highly planar which endowed the high intra-charge transfer mobility (Bao et al, 2020). DPP-based materials have often exhibited extraordinarily strong π-π interaction and aggregation properties between the neighboring DPP moieties, resulting in the materials having beneficial properties for inter-charge transfer mobility.…”

Recent advances in the application of isoindigo derivatives in materials chemistry

“…Recently, diketopyrrolo [3,4-c]pyrrole (DPP) derivatives, which are highly conjugated electron-withdrawing heterocycles with high charge conductivity, broad absorption spectrum, photostability, and thermal stability have attracted considerable interest of researchers in the field of organic electronics [92][93][94]. Isoindigo derivatives have similar characteristics.…”
