  • Publication number: 20110084243
    Abstract: Chemical light producing systems and the chemiluminescent formulations contained therein are taught which exhibit reduced hydrolysis and thereby are characterized by an inherently long shelf-life and commercial viability. By replacing the typical oxalate ester, e.g. (bis{3,4,6-trichloro-2-[(pentoxy)carbonyl]phenyl}oxalate) with a branched chain oxalic acid ester represented by the general formula: wherein the group designated as R contains from 4-15 carbons, wherein the carbon of attachment of R to the oxygen is via a primary carbon, and wherein substructure A is composed of substituents selected from the group including alkyl chains, alkyl rings, aromatic rings and combinations thereof such that R is nonlinear, water hydrolysis of the oxalate ester is retarded. This retardation of the hydrolysis changes the storage constraints of the oxalate ester.

    Abstract: This invention publishes new usages of kinds of carbonic ester compounds. The new usage described in this invention is related to the application of carbonic ester compounds in the preparation of solvents for chemiluminescent systems. This invention also provides luminescent compositions, luminescent liquids and oxidized liquids that contain carbonic ester compounds. Chemiluminescent compositions containing carbonic ester compounds can decrease reaction pressure effectively, facilitate reaction balance heading to luminescence reaction, generate larger luminescent output without adding catalyst, decrease the dosage of catalyst or not need adding catalyst, decrease influences of over-high output at the reaction start caused by catalyst on whole luminescent time, and ensure stable light output from luminescent compositions. Carbonic ester compounds, especially long carbon chain carbonic ester, have the characters of non-toxic and high flash point, and have suitable solubility on ordinary bis oxalate ester.

  • Patent number: 7147801
    Abstract: Disclosed is an ink composition suitable for ink jet printing comprising a luminescent compound, a solvent, and an energy active compound, and optionally a non-luminescent colorant. The energy active compound, when exposed to energy, generates one or more active species that can react with the luminescent compound to alter one or more of the characteristics of the luminescent compound. The luminescent compound can be colored or colorless. Also disclosed is a method for marking substrates comprising providing a mark comprising a luminescent compound and an energy active compound. Further disclosed is a jet ink composition suitable for printing on substrates authentication or security marks which can be rendered unreadable. The luminescence of the mark is quenched and the visible color is changed when irradiated with a light.

  • Patent number: 7052631
    Abstract: The present invention teaches a chemiluminescent device along with a process for its production. The invention specifically relates to a chemiluminescent article of manufacture which includes a containment device and chemical system, both of which may be selected so as to be particularly susceptible to environmental degradation subsequent to their use. In a preferred embodiment the chemiluminescent device is categorized as being biodegradable, i.e. designed to be capable of losing its physical form and re-entering the environment.

  • Patent number: 7018802
    Abstract: Electrochemiluminescent-labels and enzyme substrates, which preferably are conjugated, are used in immunoassays and electrochemiluminescence is generated catalytically. In conventional electrochemiluminescence immunoassays, an anti-analyte antibody molecule can give rise to typically 6–8 electrochemiluminescence-active ruthenium atoms, while in the present invention, each enzyme-labeled anti-analyte molecule can give rise to thousands of electrochemiluminescence-active ruthenium atoms per second. An exemplary immunoassay is based on a catalytic process employing ?-lactamase-conjugated anti-analytes which enzymatically hydrolyze electrochemiluminescent-labeled substrates, making them strongly electrochemiluminescent. The electrochemiluminescence signal generated by each anti-analyte molecule (i.e., each analyte molecule) is much greater than with the conventional method. Accordingly, greater sensitivity can be gained in the measurement of low concentrations of a given immunoassay analyte.

  • Patent number: 6872828
    Abstract: Novel compounds comprising a C—C double bond substituted at one carbon with two sulfur atom-containing groups are disclosed. The compounds are useful in methods and compositions for generating chemiluminescence rapidly by reaction with a peroxidase enzyme and a peroxide. The chemiluminescence thus produced can be used as a detectable signal in assays for peroxidase enzymes or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.
