A regioregular terpolymer that combines electron-deficient diketopyrrolopyrrole and benzothiadiazole units with an electron-rich dithienopyrrole unit is presented. In solar cells, the terpolymer affords an open circuit voltage of 0.52 V and a power conversion efficiency of 3.7% with a spectral response up to 1050 nm.

The design of fluorogenic probes for a Halo tag is highly desirable but challenging. Previous work achieved this goal by controlling the chemical switch of spirolactones upon the covalent conjugation between the Halo tag and probes or by incorporating a "channel dye" into the substrate binding tunnel of the Halo tag. In this work, we have developed a novel class of Halo-tag fluorogenic probes t...

Correction for ‘Effects of alkyl chains benzothiadiazole-based conjugated polymers on the photovoltaic performance non-fullerene organic solar cells’ by Chao Wang et al. , Polym. Chem. 2023, 14 616–622, https://doi.org/10.1039/D2PY01473D.

Furan substituted diketopyrrolopyrrole (DBF) combined with benzothiadiazole based polymer semiconductor PDPP-FBF has been synthesized and evaluated as an ambipolar semiconductor in organic thin-film transistors. Hole and electron mobilities as high as 0.20 cm(2) V(-1) s(-1) and 0.56 cm(2) V(-1) s(-1), respectively, are achieved for PDPP-FBF.

Nitrogen-bridged donor-acceptor multifused dithienopyrrolobenzothiadiazole (DTPBT) and dibenzothiadiazolopyrrolothiophene (DBTPT) were successfully synthesized by intramolecular Cadogan annulation. The electron-deficient benzothiadiazole unit in DTPBT can be converted to benzoselenadiazole and quinoxaline moieties through reduction/cyclization to generate dithienopyrrolobenzoselenadiazole (DTPB...

Abstract Solution‐processing has the potential to reduce cost and energy requirements in fabrication of organic light‐emitting diode (OLED) devices. In non‐doped emissive layers, polymers are commonly used but often suffer from batch‐to‐batch variation. Oligomers, which have precise molecular structures, avoid this problem maintain favourable film‐forming properties that possess. We present thr...

Two benzothiadiazole derivatives annulated with 2-(1,3-dithiol-2-ylidene)malonitrile in the 4,5-position were prepared by a one-step procedure, and investigated as end-groups non-fullerene acceptors for indoor photovoltaic applications.

The synthesis of three new gold(I) benzothiadiazole derivatives has been carried out by the reaction 4-ethynyl-7-(4-nonylphenyl)benzo[c] [1,2,5]thiadiazole (L) with different gold(I)-PR3 (PR3 = triethylphosphane (2), triphenylphosphane (3) and tri-1-naphthylphosphane (4)) sources their light emitting properties thoroughly investigated. compounds display denoted luminescence fluorescence quantum...
