An air-stable binary Ni(0)–olefin catalyst

by Lukas Nattmann

Nature Catalysis, Published online: 09 December 2019; doi:10.1038/s41929-019-0392-6

Nickel complexes are of ever-increasing importance in organic synthesis; however, unstable Ni(COD)2 is still the main Ni(0) source used. Here the authors report a solution to this long-standing issue: an air stable Ni(0) complex that acts as a general precatalyst for numerous nickel-catalysed reactions.

How Pranksters Tricked Twitter-Scraping Sites Into Copyright Infringement

by EditorDavid
An anonymous reader shares a remarkable story from Fortune's Data Sheet newsletter: The story begins on Dec. 3, when an artist going by @Hannahdouken on Twitter posted an image of hand-drawn text reading, "This site sells STOLEN Artwork, do NOT buy from them!" And asked followers to reply that they wanted the image on a shirt. They were testing a theory. For years, artists posting their work online have found the art turned into t-shirts and other merch without permission or compensation. The theory was that this was being done by automated bots that combed Twitter for images with such enthusiastic replies, and then automatically created merch on sites such as Gearbubble, copthistee, and Teeshirtpublic... Sure enough, automated bots picked up @Hannahdouken's image and placed it on t-shirts... They report that other Twitter users then took the stunt even further, including one who "had a theory: See if he could bait the bots into copyright infringement, and just maybe, a pricey lawsuit." So they produced a drawing of a particularly sassy Mickey Mouse with the caption "This is NOT a parody. We committed copyright infringement and want to be sued by Disney." His version of the stunt succeeded spectacularly. First, the bots came out of the woodwork, drawn by hundreds of tweets from people saying they wanted the image on a t-shirt. Then other artists repeated the trick with infringing images including Pikachu, Mario, and the Coca-Cola logo....

Subtle Molecular Tailoring Induces Significant Morphology Optimization Enabling over 16% Efficiency Organic Solar Cells with Efficient Charge Generation

Advanced Materials Subtle Molecular Tailoring Induces Significant Morphology Optimization Enabling over 16% Efficiency Organic Solar Cells with Efficient Charge Generation

High‐efficiency organic solar cells are achieved through the use of a new electron acceptor AQx‐2 with a quinoxaline‐containing fused core. The increase in performance is attributed to the optimized phase separation morphology that significantly boosts hole transfer and suppresses geminate recombination. The power conversion efficiency of these devices, 16.4%, is the highest certified value for binary organic solar cells.


Abstract

Manipulating charge generation in a broad spectral region has proved to be crucial for nonfullerene‐electron‐acceptor‐based organic solar cells (OSCs). 16.64% high efficiency binary OSCs are achieved through the use of a novel electron acceptor AQx‐2 with quinoxaline‐containing fused core and PBDB‐TF as donor. The significant increase in photovoltaic performance of AQx‐2 based devices is obtained merely by a subtle tailoring in molecular structure of its analogue AQx‐1. Combining the detailed morphology and transient absorption spectroscopy analyses, a good structure–morphology–property relationship is established. The stronger π–π interaction results in efficient electron hopping and balanced electron and hole mobilities attributed to good charge transport. Moreover, the reduced phase separation morphology of AQx‐2‐based bulk heterojunction blend boosts hole transfer and suppresses geminate recombination. Such success in molecule design and precise morphology optimization may lead to next‐generation high‐performance OSCs.
