20120035293 | ON-DEMAND PHOTOINITIATED POLYMERIZATION - Compositions and methods for adjustable lenses are provided. In some embodiments, the lenses contain a lens matrix material, a masking compound, and a prepolymer. The lens matrix material provides structure to the lens. The masking compound is capable of blocking polymerization or crosslinking of the prepolymer, until photoisomerization of the compound is triggered, and the compound is converted from a first isomer to a second isomer having a different absorption profile. The prepolymer is a composition that can undergo a polymerization or crosslinking reaction upon photoinitiation to alter one or more of the properties of the lenses. | 02-09-2012 |

20150344495 | PROCESS OF MAKING DIFLUOROTHIENOTHIOPHENE BASED CONJUGATED POLYMERS - A method of producing a monomer wherein the method begins by dissolving 3-fluoro-4,6 dihydrothieno[3,4-b]thiophene in a solvent to create a solution. An initiator is then added to the solution to produce an initiated solution. This is followed by adding a fluorinated chemical to the initiated solution to produce 2,3-difluoro-4,6-dihydrothieno[3,4-b]thiophene. 2,3-difluoro-4,6-dihydrothieno[3,4-b]thiophene is then oxidized with an oxidant to produce 2,3-difluorothieno[3,4-b]thiophene. 2,3-difluorothieno[3,4-b]thiophene is then bromoated to produce 4,6-dibromo-2,3-difluorothieno[2,3-c]thiophene. The final step involves debrominating 4,6-dibromo-2,3-difluorothieno[2,3-c]thiophene and adding an aryl group to produce the monomer | 12-03-2015 |
