A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes
Angewandte Chemie International Edition, EarlyView.We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

Harnessing plant‐based platform for low‐cost cellulosic sugar recovery from bioenergy crops
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The price of pure cellulase enzyme for the recovery of fermentable cellulosic sugars is one of the major challenges that limit the commercialization of second‐generation biofuels and bio‐based products. This work shows a means to greatly reduce the cost of cellulases. The abundant capacity of plants to synthesize and hyperaccumulate transgenic
