1 day ago · Alkenes are readily available feedstocks and serve as ideal starting materials for diverse transformations in organic synthesis. The asymmetric intermolecular 1,2-difunctionalization of alkenes, enabling the simultaneous installation of two vicinal new bonds in one step, provides a powerful tool for transforming the alkene feedstocks into chiral complex molecules. 33 – 43 On the other hand ...
4 days ago · The pursuit of high-performance narrowband blue organic light-emitting diodes (OLEDs) is of paramount importance in both academic research and industrial applications. While obvious strides have been made in the design of narrowband blue emitters, the development of appropriate host materials has evidently trailed behind. Herein, we introduce a medium-ring strategy for crafting host molecules ...

3 days ago · Dual-ion batteries (DIBs) are becoming an important technology for energy storage. To overcome the disadvantages of traditional electrodes and electrolytes, here we assemble a dual-carbon DIB with nanodiamond (ND)-modified crimped graphene (DCG) and electrolyte. The DCG anode and cathode realize high capacities of 1121 mA h g–1 and 149 mA h g–1, respectively, at 0.1 A g–1. The ...
