摘要:
A new class of alpha-cyanomethine and alpha-cyanopolymethine dyes is provided having moieties which serve for the covalent attachment to biological substrates and resulting in the fluorescent labeling of the substrates. The labeled substrates are useful in analytical techniques for the detection and measurement of biological and clinical compounds of interest. Of particular interest is a class of methine molecules which are non-fluorescent in buffer solutions but intensely fluoresce when they enter a cell.
摘要:
A novel panchromatic electrophotographic recording element has an electrically conducting substrate and one or more photoconducting layers. The photoconducting layer contains one or more binders, several charge carrier-producing compounds or sensitizers, one or more charge carrier-transporting compounds (photoconductors) and, if required, additives. The sensitizers themselves are Victoria Blue FB (C.I. 44045), Crystal Violet FN (C.I. 42555), Rhodamine FB (C.I. 45170), Astrazone Orange R (C.I. 48040) and/or Astrazone Orange G (C.I. 48035), which are used together with naphtholactam dyes and/or with isoindolenine dyes. The naphtholactam dyes have one or more chromophores of the general basic structure ##STR1## in the molecule, and the isoindolenine dyes have one or more chromophores of the general basic structure ##STR2## in the molecule.
