“…Our observations highlight the crucial role played by molecular structure/architecture and thin film morphology in the performance of organic solar cells and field-effect transistors, 42,58 Exchange of the central benzothiadiazole acceptor by an isoindigo moiety resulted in deeper HOMO-LUMO energy levels, enabling higher open-circuit voltages to be reached in bulk heterojunction organic solar cells.…”

“…squaraine, 17 benzotriazole, 18 alkyl cyanoacetate, 19 diketopyrrolopyrrole, 20 benzothiadiazole, 21 and isoindigo 22 ), most often combined with electron-donating oligothiophenes or arylamine units, have been developed over the years. [37][38][39][40][41][42][43] Further clarification of the molecular architecture -(device) property relationships is required, though, to fully exploit the synthetic versatility toward top-efficiency devices. Among the electron-poor components, isoindigo (IID) is a promising molecular building block for solar celland transistor applications because of its straightforward large-scale synthesis, strong light absorption, photochemical stability and stacking tendency.…”

“…To establish a correlation between molecular structure and various properties such as PCE, Detrembleur et al studied a series of isoindigo-based small molecules by manipulating the side chain (linear vs branched) 18 and the overall architecture (linear vs propeller-like). 19 Despite an improvement to charge transport, the PCE remained below 2%, nonetheless, the improved PCE based on the series was attributed to the more favourable charge separation which was linked to morphology. More recently, Jung et al achieved a PCE of 4.33% using a diketopyrrolopyrrole flanked isoindigo small molecule.…”
