A composition comprising a polymer backbone and at least one side group, wherein the side group comprises a benzene ring-based chromophore comprising a ketone at the 1-position, a substituted or unsubstituted amino group at the 2-position, and an oxygen atom at the 3-position of the benzene ring having the following formula: wherein R1 is H, an alkyl group, or comprises an amino acid moiety or derivative thereof; R2 and R3 are individually H, alkyl, or any moiety with a vinyl functionality; R4 is an alkyl group, any moiety with a vinyl functionality, a counterpart alkylβne group, or a sugar moiety; and X is an optional electron-donating group linked to the benzene ring at the 4, 5, or 6 position. The chromophore is a kynurenine-based compound. Methods of making and using the composition are also provided. The composition can be used in an ophthalmic lens or device for protecting the retina by blocking UV rays and filtering violet rays.
一种由聚合物骨架和至少一个侧基组成的组合物,其中侧基包括基于苯环的发色团,该发色团在苯环的 1 位上包括一个酮,在 2 位上包括一个取代或未取代的氨基,在 3 位上包括一个氧原子,该发色团具有下式:其中 R1 是 H、烷基或包含氨基酸分子或其衍生物;R2 和 R3 分别是 H、烷基或任何具有乙烯基官能团的分子;R4 是烷基、任何具有乙烯基官能团的分子、对应的烷基β炔基或糖分子;X 是在 4、5 或 6 位与苯环相连的任选电子供体。发色团是一种犬尿氨酸基化合物。还提供了制造和使用该组合物的方法。该组合物可用于眼科镜片或装置中,通过阻挡紫外线和过滤紫外线来保护视网膜。
