To achieve efficient non-fullerene organic solar cells, it is important to reduce the voltage loss from optical bandgap open-circuit of cell. Here we report a highly cell with high 1.08 V and small 0.55 V. The performance was enabled by novel wide-bandgap (2.05 eV) donor polymer paired narrow-bandgap (1.63 small-molecular acceptor (SMA). Our morphology characterizations show that both SMA can maintain crystallinity in blend film, resulting crystalline domains. As result, our cells realize an...

A new organocatalytic transfer hydrogenation strategy for the asymmetric synthesis of 1,1-diarylethanes is described. Under mild conditions, a range substituted with an o-hydroxyphenyl or indole unit could be obtained excellent efficiency and enantioselectivity. We also extended protocol to unprecedented hydroarylation 1,1-diarylalkenes indoles highly enantioenriched 1,1,1-triarylethanes bearing acyclic all-carbon quaternary stereocenters. These diaryl- triarylethanes exhibit impressive...
Abstract Single-atom catalysts have been widely investigated for several electrocatalytic reactions except electrochemical alcohol oxidation. Herein, we synthesize atomically dispersed platinum on ruthenium oxide (Pt 1 /RuO 2 ) using a simple impregnation-adsorption method. We find that Pt has good activity towards methanol oxidation in an alkaline media with mass is 15.3-times higher than of commercial Pt/C (6766 vs. 441 mA mg ‒1 ). In contrast, single atom carbon black inert. Further, the...

Herein, interconnected nanoarrays consisting Co–Ni bimetallic metaphosphate nanoparticles embedded a carbon matrix (Co 2− x Ni P 4 O 12 ‐C) are fabricated through mild phosphorylating process cobalt–nickel zeolitic imidazolate frameworks (CoNi‐ZIF). Density functional theory calculations...

Abstract A versatile π‐extension reaction was developed based on the three‐component cross‐coupling of aryl halides, 2‐haloarylcarboxylic acids, and norbornadiene. The transformation is driven by direction subsequent decarboxylation carboxyl group, while norbornadiene serves as an ortho ‐C−H activator ethylene synthon via a retro‐Diels–Alder reaction. Comprehensive DFT calculations were performed to account for catalytic intermediates.
Abstract Humidity is known to be inimical the halide perovskites and thus typically avoided during fabrication. The poor fundamental understanding of chemical interactions between water precursors hampers further development perovskite fabrication in ambient atmosphere. Here, we disclose a key finding that could promote formation lead complexes, which when uncontrolled would make their way into large intermediate fibrillar crystallites discontinuous films unfavorable for photovoltaics among...

The efficiency of the oxygen evolution reaction (OER) in acidic media is severely limited by poor stability, low activity, and high cost available catalysts. Enhancing intrinsic activity while maintaining stability reducing reliance on precious metals crucial. typical adsorbate mechanism (AEM) leads to overpotentials making transition alternative mechanisms, such as lattice (LOM) or oxide path (OPM), highly desirable due their lower overpotentials. Here, we combine density functional theory...

Novel planar chiral ferrocene nucleophilic catalysts (Fc-PIP) containing both central and elements were designed synthesized for catalytic enantioselective acyl transfer of secondary alcohols. A remarkably efficient catalyst with high selectivity factors (up to S = 1892) was identified. Comparing the combination chirality revealed a strong requirement "matched" elements, indicating that stereogenic center imidazole rings should present itself on same face as ferrocenyl fragment; otherwise,...
