Synthesis of a polythieno[3,4-b]thiophene derivative with a low-lying HOMO level and its application in polymer solar cells

A planar benzodithiophene with lower HOMO was copolymerized with the thieno[3,4-b]thiophene unit to obtain a new low band gap polymer of PBDPTT-C, which exhibited a higher open-circuit voltage (Voc) of 0.8 V and a promising efficiency of 5.2%.

Synthesis of alkylated benzo[2,1-b:3,4-6′]dithiophenes by annulative coupling and their direct arylation under palladium catalysis

The annulative coupling of 3,3′-diiodo-2,2′-bithiophene with internal alkynes efficiently proceeds in the presence of a palladium catalyst to afford the corresponding benzo[2,1-b:3,4-b′]dithiophene derivatives. The dithiophenes also undergo palladium-cata

Dithienopyrrole Derivatives with Nitronyl Nitroxide Radicals and Their Oxidation to Cationic High-Spin Molecules

Three 1 N-phenyl nitronyl nitroxide (NN) 4-substituted dithieno[3,2-b:2′,3′-d]pyrrole (DTP) derivatives with R1=4-phenyl-, 4H-, and 4-methylthiothiophenyl- (R12DTP-Ph-NN, R1=H, Ph and MeSTh) were designed, synthesized and

Substantial photovoltaic response and morphology tuning in benzo[1,2-b:6,5-b′]dithiophene (bBDT) molecular donors

The influence of solubilizing substituents on the photovoltaic performance and thin-film blend morphology of new benzo[1,2-b:6,5-b′]dithiophene (bBDT) based small molecule donor semiconductors is investigated. Solar cells based on bBDT(TDPP)2-PC71BM with two different types of side chains exhibit high power conversion efficiencies, up to 5.53%. This journal is the Partner Organisations 2014.

Hypervalent iodine(III): selective and efficient single-electron-transfer (SET) oxidizing agent

In 1994, we first determined the single-electron-transfer (SET) oxidation ability of phenyliodine(III) bis(trifluoroacetate) (PIFA) toward phenyl ethers, affording the corresponding aromatic cation radicals. Since then, hypervalent iodine(III) has been utilized as a selective and efficient SET oxidizing agent that enables a variety of direct C-H functionalizations of aromatic rings in electron-rich arenes under mild conditions. We have now extended the original method to work in a series of heteroaromatic compounds such as thiophenes, pyrroles, and indoles. The investigations and results obtained since the start of this century are summarized in this article.
