3 results about "Halogenated ether" patented technology

Organotin compositions having the formula RSnL3 and corresponding synthetic methods are described. R includes aromatic, cyclic and / or halogenated ether moieties, or polyethers, and L includes hydrolysable groups. The organotin compositions may be formed as radiation-patternable coatings on substrates. The coatings may have an average thickness from about 1 nm to about 75 nm and have the formula RSnOn(OH)3-2n, forming an oxo-hydroxo network, where R is a hydrocarbyl ether group with 1 to 30 carbon atoms and 0<n<3 / 2, wherein regions of the coating are soluble in 2-heptanone in a puddle development step following a bake at 150° C. for 120 seconds. The coatings may be radiation-patternable using UV, EUV or ion beam radiation, and corresponding methods are described.

A supramolecular ionic liquid, a solid-state electrolyte membrane, a solid-state lithium metal battery, and an apparatus are provided. The supramolecular ionic liquid of this disclosure has a benzophenanthrene structure represented by formula (I), where R1 is selected from ether groups, polyether groups, halogenated ether groups, or halogenated polyether groups having 1 to 16 carbon atoms; and R2 is selected from ether groups or polyether groups having 1 to 16 carbon atoms. The supramolecular ionic liquid of this disclosure has an ionic conductivity as high as 10−3 S / cm at room temperature. A solid-state electrolyte membrane made therefrom also has an ionic conductivity as high as 10−3 S / cm at room temperature. This is close to performance of a liquid electrolyte, proposing a solution to the problem of low ionic conductivity in existing solid-state electrolytes.
