Patent number: 7566783Abstract: A new approach is described to making luminophores which display long emission wavelengths, long decay times, and high quantum yields. These luminophores are covalently linked or otherwise closely associated pairs with a long lifetime resonance energy transfer (RET) donor e.g., a ruthenium (Ru) metal-ligand complex, and a long wavelength acceptor, e.g., Texas Red. The donor and acceptor can be covalently linked by, e.g., poly-proline spacers. The long lifetime donor results in a long lived component in the acceptor decay which is due to RET. The quantum yield of the luminophores approaches that of the higher quantum yield acceptor, rather than the lower quantum yield typical of metal-ligand complexes. The emission maxima and decay time of such tandem luminophores can be readily adjusted by selection of the donor, acceptor and distance between them. Luminophores with these useful spectral properties can also be donor-acceptor pairs brought into close proximity by some biochemical association reaction.Type: GrantFiled: July 23, 2001Date of Patent: July 28, 2009Inventor: Joseph R Lakowicz

Publication number: 20030195378Abstract: In a process for the hydroformylation of ethylenically unsaturated compounds, at least one complex of a metal of transition group VIII. with at least one phosphorus-, arsenic- or antimony-containing compound as ligand is used as hydroformylation catalyst, where the compound used as ligand in each case comprises two groups which comprise a P, As or Sb atom and at least two further hetero atoms and are bound to a xanthene-like molecular framework. New compounds of this type and catalysts which comprise at least one complex of a metal of transition group VIII. with at least one such compound as ligand are also provided.Type: ApplicationFiled: March 11, 2003Publication date: October 16, 2003Inventors: Wolfgang Ahlers, Dag Wiebelhaus, Rocco Paciello, Michael Bartsch, Robert Baumann, Dieter Vogt, Alison Hewat

Publication number: 20030144434Abstract: The invention relates to chemical products which are suited for use as co-catalysts and which can be obtained by reacting a compound of formula (I), M1R1R2(R3)m with a compound of formula (II), (R4X)q-(G)*(M2R5R6)g. In formula (I), R1, R2 and R3 are the same or different and represent a hydrogen atom, C1-C20 alkyl, C1-C20 alkyl halide, C6-C20 aryl, C6-C20 aryl halide, C7-C40 arylalkyl, C7-C40 arylalkyl halide, C7-C40 alkylaryl or C7-C40 alkylaryl halide; M1 represents an element of the second or third main group of the periodic table of elements, and; m equals 0 or 1, whereby m is equal to 1 when M1 represents an element of the third main group, and m is equal to 0 when M1 represents an element of the second main group.Type: ApplicationFiled: November 20, 2002Publication date: July 31, 2003Inventor: J?ouml;rg Schottek

Publication number: 20030097013Abstract: Nitrogen containing analogs of Copper II &bgr;-diketonates which analogs are more stable source reagents for copper deposition when substantially free of solvents of excess ligands. The nitrogen containing analogs replace -O- with —N(R″)—wherein R″ is an alkyl group having from one to four carbon atoms. Replacement of each -O- is preferred although replacement of one -O- per cyclic ring is sufficient to improve stability of the copper source reagents. The source reagent can be purified by sublimation to remove solvents and excess ligands prior to semiconductor processing.Type: ApplicationFiled: April 12, 2002Publication date: May 22, 2003Applicant: Applied Materials, Inc.Inventors: Ling Chen, Barry Chin
