标题 :Convergent synthesis of multiporphyrin light-harvesting rods
发明人：LINDSEY JONATHAN S; LOEWE ROBERT S
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.

标题:The synthesis of extended bis(ethylenedithio)tetrathiafulvalene derivatives and their dihydroxyl analogues

摘要:The present invention describes the synthesis of six novel derivatives of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF), utilising the recently developed reaction of 1,8-diketones with Lawesson's reagent. These new BEDT-TTF derivatives (1)-(6) have potential to delocalise the positive charges formed during change-transfer salts to the peripheral. In addition to their positive charge delocalisation feature, the compounds (1)-(3) have the potential of being introduced hydrogen bonding groups and the compound (4)-(6) already have hydrogen bonding hydroxyl groups. All the new BEDT-TTF (7) derivatives described in this invention have shown comparative CV measurements with the BEDT-TTF. Each of these bis(ethylenedithio)tetrathiafulvalene derivatives of the present invention has a unique and novel structure which can not be found in the prior art and is useful for the development of new organic charge-transfer complexes.

标 题:In situ binary synthesis of biologically effective molecules
发明人：ECKER DAVID J
权利人:ISIS PHARMACEUTICALS INC; ECKER DAVID J
摘要:A plurality of oligonucleotides are caused to bind specifically to target nucleic acid which is predictive of a disease state or a biological condition within cells containing the target nucleic acid. The respective oligonucleotides, which may be functionilized or may be present in the form of oligonucleotide analogs, carry with them a plurality of synthons. Such synthons, which may be identiphores, toxiphores, or other precursors to biologically effective molecules, interact when specific binding of the respective oligonucleotides occurs at sites adjacent to each other on the target nucleic acid. The resulting interaction gives rise to the synthesis, generation or release of highly active biological molecules in situ in the cell in which the specific binding takes place. This permits the use of extraordinarily toxic molecules for use in killing cells containing the target nucleic acids. Imaging and other uses are also provided by the present invention.

标题:High pressure synthesis of sulfur-selenium fulvalenes
发明人：OKAMOTO YOSHIYUKI; WOJCIECHOWSKI PIOTR S
权利人:KOPPERS CO INC
摘要:A process is disclosed for one-step preparation of sulfur-selenium fulvalenes by reaction of an acetylenic compound with carbon selenide sulfide or with a mixture of carbon diselenide and carbon disulfide under pressures of at least about 1,000 atmospheres. Fulvalene compounds made by the process are characterized in having at least one sulfur atom and at least one selenium atom in the ring structure of the fulvalene compound. Substituted diselenadithiafulvalenes made by this process are precursors to very pure diselenadithiafulvalene which is useful in preparing charge-transfer salts.
