Polyfluoroaromatic derivatives for liquid lenses

Abstract

A liquid lens including a first liquid comprising a polyfluoroaromatic compound represented by formula (I): F-(aromatic)-Y—R. 'x' is within a range of from 2 to 5. Y is one of CH, Si(Alk), Ge(Alk), O, and S. “Alk” is a linear aliphatic chain. Ris any organic group, but can be one of a linear aliphatic chain, a cycloaliphatic, a fluorocycloaliphatic, and an aromatic residue. “Aromatic” is any six carbon aromatic ring. Examples of the chemical compound represented by formula (I) include butylpentafluorobenzene; dimethylnonafluorohexylpentafluorophenylsilane; trimethylpentafluorophenylgennane; butoxypentafluorobenzene; cyclopentoxypentafluorobenzene; 1-n-octyloxypentafluorobenzene; cyclooctyloxypentafluorobenzene; 1-n-dodecyloxypentafluorobenzene; cyclopentylpentafluorophenylsulfide; phenoxypentafluorobenzene; 2,4-difluoroanisole; and heptafluoropentyloxypentafluorobenzene. The first liquid has a density in a range of from 0.95 g/mL to 1.35 g/mL (at 20° C.). The liquid lens further includes a second liquid that forms an interface with the first liquid. The second liquid can be substantially free of water.
