Abstract: A safe, simple, and selective method and reagent for deoxyfluorination is disclosed. With the method and reagent disclosed herein, organic compounds such as carboxylic acids, carboxylates, carboxylic acid anhydrides, aldehydes, and alcohols can be fluorinated by using the most common nucleophilic fluorinating reagents and electron deficient fluoroarenes as mediators under mild conditions, giving corresponding fluoroorganic compounds in excellent yield with a wide range of functional group compatibility and easy product purification. For example, directly utilizing KF for deoxyfluorination of carboxylic acids provides the most economical and the safest pathway to access acyl fluorides, key intermediates for syntheses of peptide, amide, ester, and dry fluoride salts.

Abstract: The present invention relates to a black matrix mask, a method for manufacturing a black matrix, and an application thereof. The black matrix mask includes a light-shielding layer having a predetermined transmission rate and coated along an edge of a black matrix pattern of the black matrix mask. The present invention also provides methods for manufacturing a black matrix, a color filter, an array substrate, and a liquid crystal display device. The method for manufacturing the black matrix includes: Step 100: using the black matrix mask to subject a black matrix material layer on a base plate to exposure; Step 200: subjecting the exposed black matrix material layer to development; and Step 300: subjecting the developed black matrix material layer to baking to finally form a black matrix on the base plate.

Abstract: Discovering high capacity and high rate cathodic materials is of paramount importance for the further development of electrochemical energy storage devices. Reported herein is a perfluoroalkylated polymer, integrated with an electronically-conductive backbone and an electron transfer catalyst unit that can serve as a new type of cathodic material reaching practical specific capacity of 919 mAh/g at 2.5 C discharging rate and over 700 mAh/g at 16 C discharging rate. A prepolarization treatment of the cathodic materials further increases working voltage to over 2.1 V versus Li/Li+ in classical PC/LiPF6 electrolyte solution giving maximum specific capacity of 1028 mAh/g and specific energy of 2159 mWh/g.
