“…Therefore, a series of soluble triethylsilylethynyl substituted ADT end-capped with phenyl (7), thiophene (8), bithiophene (9), and perfluorophenyl (10), were reported for solution processable OTFTs. [29] An electron withdrawing perfluorophenyl F I G U R E 1 Chemical structure of ADT-based small molecular semiconductors group in triethylsilylethynyl-ADT slightly lowers both the HOMO and LUMO energy levels of molecule 10. All four compounds 7-10 have been fabricated in solution processable OTFTs by solution-shearing, droplet-pinned crystallization, and drop-casting methods.…”

“…[28][29][30] Anthradithiophene (ADT) is a thienoacene that is isoelectronic to pentacene, with five linearly-fused aromatic rings, yet considerably more stable to oxidative degradation. [31][32][33][34][35][36] For this reason, we sought to access new cyclopentannulated derivatives of anthradithiophene via the utilization of soluble ADT derivatives. ADTs were originally synthesized from regiorandom ADT-quinones and utilized as a mixture of syn and anti-isomers owing to the difficulties in separating the generated isomers.…”

Two acceptor small molecules consisting of 2-(11-oxoanthra [2,1-b]thiophen-6-ylidene)dipropanedinitrile frameworks connected by a bis(thiophen-2-ylethynyl)arene bridge were synthesized by the two-step sequence of Sonogashira cross-coupling and Knoevenagel condensation in order to investigate their performance as non-fullerene acceptors in organic solar cells. Optical, electrochemical and photovoltaic properties of new 2,2'-[2,2'-(5,5'-(arenediyl)bis(ethyne-2,1-diyl)bis(thien-5,2-diyl)) bis(11-oxoanthra[2,1-b]thiophen-6-ylidene)]dipropanedinitriles and previously studied analogs of 2,2'-[2,2'-arenediylbis(11oxoanthra[1,2-b]thiophene-6-ylidene)]dipropanedinitriles were compared to assess the effect of introducing ethynylthiophene units between the arene linker and the 2-(11-oxoanthrathio-phen-6-ylidene)propanedinitrile units. Despite the proper energy level alignment and morphology, composites of the newly synthesized compounds with the PBDB-T donor polymer demonstrate a moderate PCE of 0.54 %. The small value of the short circuit current as compared to composites with fullerene acceptors is probably due to the low electron mobility in the newly synthesized compounds. The low electron mobility, in turn, is probably cause by the LUMO localization at the edge units of the acceptor-type molecules, in contrast to the almost uniform LUMO delocalization over the whole π-conjugated system for high-performing non-fullerene acceptors such as ITIC.
