Provided are a bissulfonate compound, a preparation method therefor, an electrolytic solution and an energy storage device. The bissulfonate compound has a structure of (I) and is applied as an additive to an energy storage device, so that a stable SEI film can be formed on a surface of an anode of the energy storage device, and the decomposition of a solvent in the electrolytic solution can be suppressed. As the stable SEI film can be formed on the surface of the anode, lithium ions can be smoothly embedded and disembedded at a low temperature, thereby improving the low-temperature performance of the energy storage device. Furthermore, a sulfonate group in the bissulfonate compound can coordinate with transition metal ions to form a complex, so that the surface of the positive electrode is passivated, the dissolution of the metal ions of the positive electrode is suppressed, and the decomposition effect of the solvent by an active substance in a high oxidation state is reduced, thereby improving the electrochemical performance of the energy storage device under a high temperature condition. In an energy storage device, the bissulfonate compound can inhibit the increase of the direct current internal resistance, and improve the high temperature performance and the low-temperature performance of the energy storage device.

This application describes modified amino acids and polypeptides comprising a SO.sub.2F or CH.sub.2CH.sub.2SO.sub.2F group bound to the side chain of an amono acid or amino acid residue of a polypeptide in place of a hydrogen of a hydroxyl or amino substituent thereof. Methods of covalently binding the polypeptides to receptot sites of receptor proteins are also described herein.

A high-throughput screening methods for identifying candidate anticancer medicinal agents is described herein. The candidate anticancer medicinal agents are arylfluorosulfate compounds derived from phenolic compounds. The method involves in situ generation of the arylfluorosulfate compounds in multi-well plates by reaction of phenolic compounds in DMSO with a saturated solution of SO.sub.2F.sub.2 dissolved in a solvent such as acetonitrile, in the presence of an organic base, followed by reaction of generated fluoride ion with trimethylsilanol to form volatile trimethylsilyl fluoride. Solvents, organic base, and silyl compounds are then removed, in vacuo, to afford the arylfluorosulfate compounds suitable for biological screening in cancer cell lines without further purification.

Please replace the following substitute abstract for the abstract currently on file: Disclosed are a monomer for a polymer gel, a polymer gel and a preparation method therefor. The preparation method includes: reacting 4,4′,4″-trihydroxytriphenylmethane with tert-butyldimethylchlorosilane to obtain TPC-OTBS; reacting 4,4′,4″-trihydroxy triphenylmethane with sulfuryl fluoride in the presence of triethylamine to prepare TPC-OSO.sub.2F; and dissolving the TPC-OTBS and TPC-OSO.sub.2F in DMF, then adding DBU and ultrasonically dispersing same until uniform, and letting same stand to obtain a polymer gel. The gel obtained by the present invention can selectively adsorb an organic solvent by means of electrostatic interaction and Van der Waals force. The surface and internal morphologies of a solid material are characterized by SEM and TEM, in which the porous morphology of the solid material is found, and most of the pores are macropores.
