| 2 | Process for the preparation of dyestuffs | US442049 | 1995-05-16 | US5502171A | 1996-03-26 | Roderich Raue; Alfred Brack; Karl-Heinrich Lange |
| Dyestuffs of the formula ##STR1## in which D is the radical of an aromatic or heterocyclic diazo component andZ is the radical of an aromatic or heterocyclic coupling component,are obtained in an ecologically advantageous manner by reacting an aromatic or heterocyclic diazo components of the formulaD--NH.sub.2and a coupling component of the formulaH--Z.sub.1with a nitrite, in the presence of CO.sub.2 at a pressure of 5-100 at. The process is suitable in particular for the preparation of concentrated dyestuff solutions, because expensive operations, such as, for example, pressure permeation and reverse osmosis, can be omitted. | ||||||

| Triazabutadiene molecules as cleavable cross-linkers adapted to cross-link components with click chemistry, e.g., clickable triazabutadienes. For example, in some embodiments, the triazabutadienes feature alkyne handles attached to the imidazole portion or the aryl portion of the triazabutadienes, wherein the alkyne handles can link to azide handles (e.g., azide handles disposed on other components) via click chemistry. Also described are methods of producing said clickable triazabutadienes and methods of use of said clickable triazabutadienes. The present invention also features methods of cleaving said clickable triazabutadienes, e.g., for liberating the diazonium species for further chemical reactions. | ||||||

The triazabutadiene molecules may alternatively be cleaved in reducing conditions or as a light-catalyzed reaction. The compounds herein may be used for delivery of drugs, as part of detection systems, or for other applications such as underwater adhesive applications. | ||||||

| Triazabutadiene molecules that provide adhesive functionality, e.g., triazabutadiene molecules as underwater adhesives or water-reactive adhesives. The triazabutadiene molecules mask an aryl diazonium ion, a highly reactive chemical functionality. Once unmasked, e.g., in water, the diazonium species is adapted to react with an electron rich aryl ring that can undergo diazonium chemistry (e.g., phenol species, resorcinol species, etc.). Triazabutadienes can be used as additives in adhesive systems such as but not limited to epoxy adhesive systems. | ||||||

| This invention relates to an optical recording medium, comprising a substrate, a reflecting layer and a recording layer based on compounds of formula (I), (II), (III) or (IV). Attention is drawn to the description for the precise meanings of the substituents. Recording and playback are carried out especially at a wavelength of from 350 to 500 nm, for example using a blue laser. The recording and playback quality is excellent and allows high storage density. Likewise claimed are some novel compounds of formula (I), (II), (III) or (IV), as well as an optical recording medium comprising, in the following arrangement, a) a supporting material consisting of a reflecting metal or, preferably, of a polymer having a reflection metallic layer; b) an optical recording layer; c) a separating layer consisting of a metallic, crosslinked organometallic or dielectric inorganic substance; and c) a covering layer. | ||||||
