Abstract

This review summarizes the recent progress of DPP-based conjugated materials, including small molecules and conjugated polymers, for application in non-fullerene organic solar cells.

Theoretical Studies of Photophysical Properties of D−π−A−π−D-Type Diketopyrrolopyrrole-Based Molecules for Organic Light-Emitting Diodes and Organic Solar Cells

“…Amongst various small molecular material building blocks, such as benzofuran [22], triphenylamine (TPA) units [23], tetraphenylethylene (TPE) [24], selenophene [25], phenanthrene [26], pyrene [27], and diketopyrrolopyrrole (DPP) derivative, DPP derivatives have attracted much interest owing to their outstanding performance in OSCs, OLEDs, and FETs [28][29][30][31]. DPP-containing materials possess promising features such as strong absorption and emission in the visible region, excellent thermal and photo-stability, large Stokes shift, and straightforward synthetic modification [32][33][34][35][36]. The DPP unit is a widely recognized electron acceptor owing to its strong electron-withdrawing nature [37,38].…”

Synthesis of the diketopyrrolopyrrole/terpyridine substituted carbazole derivative based polythiophenes for photovoltaic cells

“…Because of their light weight, low cost, and exibility, p-conjugated polythiophenes (PTs) are promising candidates for various optoelectronic device applications, including polymer light-emitting devices, 1,2 electrochromic devices, 3 organic eldeffect transistors, 4,5 photovoltaic (PV) cells, [6][7][8][9][10][11][12][13][14][15] and uorescent chemosensors. [16][17][18][19] Polymer-based photovoltaic cells (PVCs) typically contain a layer comprising a blend of PT and a fullerene derivative.…”

Ground and Excited States of Bis‐4‐Methoxybenzyl‐Substituted Diketopyrrolopyrroles: Spectroscopic and Electrochemical Studies

“…Diketopyrrolopyrrole (DPP) based compounds have emerged rapidly as interesting molecules and materials for applications ranging from fluorescent probes to optoelectronic devices . The interest is stoked by their synthetic possibilities and their high thermal and photo‐stability .…”

“…Diketopyrrolopyrrole (DPP) based compounds have emerged rapidly as interesting molecules and materials for applications ranging from fluorescent probes [1][2][3][4] to optoelectronic devices. [5][6][7][8][9][10] The interest is stoked by their synthetic possibilities and their high thermal and photo-stability. [11] The planar core of these compounds (Figure 1) consists of a π-conjugated dilactam system which can be substituted with different aromatic groups at the 3-and 6-positions, and with alkyl derivatives as the Nsubstituents.…”
