Effect of furan π-bridge on the photovoltaic performance of D-A copolymers based on bi(alkylthio-thienyl)benzodithiophene and fluorobenzotriazole

The medium band gap donor-acceptor (D-A) copolymer J61 based on bi(alkylthio-thienyl)benzodithiophene as donor unit and fluorobenzotriazole as acceptor unit and thiophene as π-bridge has demonstrated excellent photovoltaic performance as donor material in nonfullerene polymer solar cells (PSCs) with narrow bandgap n-type organic semiconductor ITIC as acceptor. For studying the ...

Recyclable bifunctional aluminum salen catalyst for CO2 fixation: the efficient formation of five-membered heterocyclic compounds

A variety of unique Al(salen) complexes functionalized by imidazolium-based ionic liquid (IL) moieties with the salen ligand at the two sides of 3,3′-position have been successfully prepared, rather than familiar 5,5′-position reported previously. The catalytic activity obtained by these bifunctional catalysts could be superior to those of the binary type catalysts in the formation ...

High resolution scanning optical imaging of a frozen planar polymer light-emitting electrochemical cell: an experimental and modelling study

Light-emitting electrochemical cells (LECs) are organic photonic devices based on a mixed electronic and ionic conductor. The active layer of a polymer-based LEC consists of a luminescent polymer, an ion-solvating/transport polymer, and a compatible salt. The LEC p-n or p-i-n junction is ultimately responsible for the LEC performance. The LEC junction, however, is still poorly ...

Large-scale preparation of fernwort-like single-crystalline superstructures of CuSe as Fenton-like catalysts for dye decolorization

A simple green hydrothermal template-free method was developed to prepare single-crystalline superstructures of fern-wort-like copper selenide (CuSe) in large-scale by using polyvinylpyrrolidone (PVP) as both reductant and surfactant for the first time. Time-dependent morphologic evolution was made in order to explore the formation mechanism of the as-prepared product. The copper ...

Sensitive detection of DNA methyltransferase activity based on supercharged fluorescent protein and template-free DNA polymerization

DNA methylation, catalyzed by DNA methyltransferases (MTases), is a key component of genetic regulation, and DNA MTases have been regarded as potential targets in anticancer therapy. Herein, based on our previously developed DNA-mediated supercharged green fluorescent protein (ScGFP)/graphene oxide (GO) interaction, coupled with methylation-initiated template- free DNA ...
