Aromatic compounds having a perfluoroalkyl group and a gelling agent for gelling an organic liquid which is composed of any one of them. This gelling agent can gel many kinds of organic liquids by adding a small amount thereof.

Aromatic compound gelling agent having perfluoroalkyl group

A compound represented by the following formula (1) is provided as a gelling agent for gelatinizing a liquid organic compound: wherein n and m are each independently an integer of 2 to 18, Rand Rare each independently a single bond or a branched or linear alkylene group having 1 to 6 carbon atoms, Ris a branched or linear alkylene group having 3 to 18 carbon atoms, and Zand Zare each independently a phenylene group or a biphenylene group.

Gelling agent and gel

The electrolyte solution for a lithium ion secondary battery according to the present invention contains a nonaqueous solvent, a lithium salt and a compound represented by the general formula (Z) shown below. Thereby, a lithium ion secondary battery having high battery characteristics and simultaneously achieving a high safety as well can be provided.R&#x2014;SO&#x2014;Ar&#x2014;O&#x2014;R&#x2003;&#x2003;(Z)wherein Ardenotes a substituted or nonsubstituted divalent aromatic group having 5 to 30 atoms of the nucleus(es); Rdenotes a saturated or unsaturated monovalent hydrocarbon group having 1 to 20 carbon atoms; and R denotes a saturated or unsaturated monovalent hydrocarbon group having a perfluoroalkyl group and having 2 to 22 carbon atoms.

Electrolyte solution for lithium ion secondary battery, lithium ion secondary battery, fluoroalkane derivative and gelling agent

To provide a gelling agent containing a fluoroalkyl derivative, a small amount of which can gelatinize or solidify various organic solvents. The gelling agent for organic liquids contains a fluoroalkyl derivative represented by the following formula: wherein each of m, n and x is a positive integer.
