摘要:
A naphthopyran compound represented by the formula B1 and B2 are selected from a phenyl, naphthyl, or heterocyclic aromatic group, or may combine to form one or more aromatic rings. B1 and B2 are optionally substituted with one or more substituents. R3, R4, R5, R6, and R10 are selected independently from hydrogen, halogen, —Ra, —OH, —ORa, —O—CO—Ra, —CN, —NO2, —SO2Ra, —SORa, —SH, —SRa, —NH2, —NHRa, —NRaRa, and —NRbRc. Any two or more of R5, R6 or R10 may combine to form a cyclic group. R7 is a mesogenic group containing at least two rings connected to each other through a covalent bond or linking unit. The linking unit is an ester, —Rd—, —O—, —ORd—, —ORdO—, —OCORd—, —OCORdO—, —S—, —CH═CH—, —CH═N—, —C≡C—, or —N═N—, where Rd is a linear or branched (C1-18)alkyl or a linear or branched (C1-18)haloalkyl group. The naphthopyran compound may be incorporated into an optical article.

摘要:
We describe a wide band variable transmission optical device, mixtures for use in such a device, and methods of making the same. The wide band optical device includes a cell comprising a guest-host mixture of a liquid crystal host and a dichroic guest dye material contained between a pair of plastic substrates. The optical device does not use polarizers. The liquid crystal host has an axis orientation that is alterable between a clear state orientation and a dark state orientation perpendicular thereto and the dichroic guest dye material includes one or more dichroic dyes. The optical device is characterized in that it exhibits a wide absorption band that is greater than 175 nm within a visible wavelength range of 400-700 nm and has a clear state transmission equal to or above 30% and a dark state transmission equal to or below 40%.
摘要:
A mixture used in photochromic devices comprises a photochromic dye and a thermoset adhesive. An optical device using the mixture may include a carrier substrate which may then be secured to another substrate or a lens. Assembly of the carrier substrate and mixture to another substrate and/or lens may be accomplished by thermoforming, lamination, insert molding or the like.
