  • Luminescence indicator including ionophoric moiety
    Patent number: 6001999
    Abstract: The invention relates to a compound having the general Formula I in which one of the groups R.sub.1,R.sub.2,R.sub.3,R.sub.4,R.sub.5,R.sub.6 and R.sub.7 represents an ionophoric moiety and the remaining groups each independently are hydrogen, a lipophilic or hydrophilic group or a reactive group for coupling to a polymer or a biomolecule, or R.sub.2 forms an aromatic ring system together with R.sub.3 and R.sub.5 forms an aromatic ring system together with R.sub.6.the compound of the invention is useful as a luminescence indicator for cations.

  • Dicyanoazulenyl and dicyanovinyl substituted furan
    Patent number: 5252757
    Abstract: A cycloadduct of the formula ##STR1## is prepared by reacting 2,2'-(2,5-furandiyldimethylidine)bis-propanedinitrile with 8-methoxypheptafulvene to form a tetrahydroazulene intermediate and then heating a solution of the tetrahydroazulene intermediate in a boiling solvent to drive off methanol.
    Type: Grant
    Filed: July 26, 1991
    Date of Patent: October 12, 1993
    Assignee: Suddeutsche Zucker-Aktiengsellschaft
    Inventors: Jorg Daub, Knut M. Rapp, Petra Seitz, Rainer Wild, Josef Salbeck
  • Dicyanovinylsubstituted furan derivatives
    Patent number: 5091538
    Abstract: The present invention refers to dicyanovinylsubstituted furan derivatives, processes for their production and their application. The new furan derivatives are represented by the general formula ##STR1## wherein x.sup.1 and x.sup.2 are equal or different and stand for H, alkyl, alkenyl, aryl, halogen, NO.sub.2 or CN.In the general formula I, n may be 0 or 1. In case of n=0, A means e.g. --CH.sub.2 OR.sup.1 (with e.g. R.sup.1 .dbd.H, alkyl or aryl).The compounds according to this invention can be used directly or in the form of their cycloadducts in several applications of electro-optical fields, e.g. for the manufacture of optical data recording systems or organic (electron) conducting materials or electron-transfer catalysts.
