Benzotrithiophene--a planar, electron-rich building block for organic semiconductors.
نویسندگان
چکیده
Several functionalized benzo[1,2-b:3,4-b':5,6-d'']trithiophenes have been synthesized and characterized. The fully planar and highly electron-rich material shows great promise as the donor constituent in donor-acceptor type copolymers for use in organic electronics. As a proof of concept, a copolymer with the electron acceptor, 2,1,3-benzothiadiazole, has been prepared. Side-chain modifications have been employed to adjust both the electron-rich character of the monomer and the solubility and processability of the polymer.

novel electron-rich fused aromatic unit, namely benzo[1,2-b:3,4b’:5,6-d’’]trithiophene (BTT), which holds promise as a building block for semiconductor materials. In comparison with the wellknown benzo[1,2-b:4,5-b’]dithiophene (BDT), quantumchemical calculations (B3LYP/6-31G*) predict the BTT unit to 40 be of similar donor strength. Thus, with R being alkyl chains, BTT is predicted to act as a ...

In the last decade, π-conjugated polymeric materials have emerged as promising semiconductors for low-cost organic optoelectronic applications, such as organic thin-fi lm transistors (OTFTs) [ 1 ] and photovoltaics (OPVs) [ 2 ] to cite two device categories. Planar π-conjugated building blocks represent a key target for highperformance polymeric semiconductors, since π-system planarization faci...
متن کاملPlanar perovskite solar cells using fullerene C70 as electron selective transport layer
Owing amongst other to its high electron mobility, fullerene C70, has been widely used as an electron transporting layer in organic solar cells. In this research, we report the use of C70 thin films as electron transport layers of planar perovskite solar cells (PSCs) using a conventional device structure. The thickness of the C70 layer has been optimized to achieve the best efficiency of 12%. I...

A novel acceptor, (3E,7E)-3,7-bis(2-oxoindolin-3-ylidene)-5,7-dihydropyrrolo[2,3-f]indole-2,6(1H,3H)-dione, was reported. Donor-acceptor (D-A) polymer semiconductors using this new building block showed high ambipolar charge transport performance with hole and electron mobilities up to 0.19 and 0.09 cm(2) V(-1) s(-1), respectively, in thin film transistors.
متن کاملEumelanin-inspired core derived from vanillin: a new building block for organic semiconductors.
An eumelanin-inspired core derived from the natural product, vanillin (vanilla bean extract) was utilized for the synthesis of eumelanin-inspired small molecules and polymer via Sonogashira cross coupling. The materials demonstrate that the methyl 4,7-dibromo-5,6-dimethoxy-N-methyl-1H-indole-2-carboxylate core can serve as a new building block for organic semiconductors.
