  • Compounds having photochemically removable protecting groups based on an electrocyclic reaction between a chromophore attached via an anilide group to a benzothiophene ring
    Patent number: 8703970
    Abstract: Disclosed herein are compounds having photoremovable protecting groups which are removed after the compounds absorbs light of a given wavelength and undergo an electrocyclic reaction between a chromophore in the compound attached via an anilide to a benzothiophene ring.
    Type: Grant

  • Photodegradation of metal chelate complexes
    Patent number: 4943357
    Abstract: A method of photodegrading a metallic chelate complex wherein ultraviolet light is directed into an aqueous solution of a metallic chelate to photodegrade the metallic chelate and isolate the metallic portion. The ultraviolet light has a wavelength of no greater than about 210 nm and the method is especially adapted for photodegrading metallic chelates in electroless nickel plating baths and metallic ethylenediamine triacetic acid to recover the metallic portions as well as reduce toxic waste.
