A hair dyeing molecule for improving the hair dyeing fastness and the hair antioxidant performance of plant dye molecules, and a synthesis method and application thereof

The application discloses a hair dyeing molecule for improving hair dyeing color fastness and hair oxidation resistance performance and a synthesis method thereof. The hair dyeing molecule is prepared by esterification or amidation reaction of a natural pigment molecule with a phenolic hydroxyl group, an alcoholic hydroxyl group, an amino group or an imino group structure and an organic acid containing an alpha, beta-carbon-carbon double bond, so as to obtain a natural pigment molecule derivative with an alpha-carbonyl carbon-carbon double bond structure. The improved pigment molecule is connected to the keratin of the hair through a chemical bond by a thiol click reaction, so that the pigment residence performance is greatly improved, and the color fastness effect is improved.

Display device and electronic device

The invention relates to a display device and an electronic device. The display device may include a display panel, a touch sensing layer, and a reflection adjustment layer. The touch sensing layer may include a touch insulating layer. The touch insulating layer may include a colorant and may cover the first light emitting region. The reflection adjustment layer may be disposed on the touch sensing layer. The reflection adjustment layer may include a first adjustment portion, which is a non-polarizing portion, and a second adjustment portion, which is a polarizing portion. The first adjustment portion may cover the first light emitting region, and the second adjustment portion may cover a second light emitting region. The display panel may be configured to emit light of a first wavelength band through the first light emitting region, and the touch insulating layer may be configured to selectively transmit light of the first wavelength band.
