Polyfluoroaromatic derivatives for liquid lenses

A liquid lens comprising:

• a first liquid comprising a polyfluoroaromatic compound represented by formula (I) below
• Fx-(aromatic)-Y—R1 (I)
• where x is within a range of from 2 to 5;
• where Y is chosen from the group consisting of CH2, Si(Alk)2, Ge(Alk)2, O, and S, where “Alk” is a linear aliphatic chain;
• where R1 is any organic group, and “aromatic” is any six carbon aromatic ring;
• and
• a second liquid, wherein the first liquid and the second liquid (i) form an interface between the first liquid and the second liquid, (ii) comprise a miscibility of less than 2% over a temperature range of from −30° C. to 85° C., and (iii) each comprise a density, the densities differing by less than 0.1 g/mL.

A method of manufacturing a liquid lens comprising:

• disposing a first liquid into a base, the first liquid comprising a polyfluoroaromatic compound represented by formula (I) below
• Fx-(aromatic)-Y—R1 (I)
• where x is within a range of from 2 to 5;
• where Y is chosen from the group consisting of CH2, Si(Alk)2, Ge(Alk)2, O, and S, where “Alk” is a linear aliphatic chain;
• where R1 is any organic group, and “aromatic” is any six carbon aromatic ring;
• and
• disposing a second liquid into the base,
• wherein the first liquid and the second liquid (i) form an interface between the first liquid and the second liquid and (ii) comprise a miscibility of less than 2% over a temperature range of from −30° C. to 85° C.;
• wherein the first liquid comprises a density in a range of from 0.95 g/mL to 1.35 g/mL (at 20° C.);
• wherein, a difference between the density of the first liquid and a density of the second liquid is less than 0.1 g/mL;
• and
• wherein a difference between a refractive index of the first liquid and a refractive index of the second liquid is in a range of from 0.02 to 0.24.
