  ‘Naturalization’ of textile disperse dyes through glycoconjugation: the case of a bis(2-hydroxyethyl) group containing azo dye

  摘要：

  A family of five strictly related glycoconjugated azo dyes (GADs), characterized by the presence of the same chromophore and a variable number (1-4) of deprotected hexose units, has been prepared by employing succinate bridges for connecting the azo dye and the sugar portions. The modulation of the hydrophilic portion determines the appreciable changes in the water solubility of GADs. In all the cases, however, hydrophobic fibres (polyester) were homogeneously dyed with GADs at temperatures lower than that used for original azo dyes, at atmospheric pressure, and avoiding the use of surfactants. Furthermore, GADs show an interesting multipurpose character leading to dyeing well also the natural fibres as, for instance, wool. The presence of a variable number of hexose units in the different GADs determines some changes in the colour intensity of dyed fabrics, but in all the cases an appreciable rubbing and water fastness were maintained.

  A process for producing silicone intraocular lenses (IOLs) capable of absorbing blue light. Intraocular lenses so produced block blue light from reaching the retina of an eye implanted with the IOL. By blocking blue light from reaching the retina, the IOL thereby prevents potential damage to the retina.

  A process for producing intraocular lenses (IOLs) capable of absorbing blue light and ultraviolet light using photo curing. Intraocular lenses so produced block blue light and ultraviolet light from reaching the retina of an eye implanted with the IOL. By blocking blue light and ultraviolet light from reaching the retina, the IOL thereby prevents potential damage to the retina.
