  • Method for separating molecules
    Patent number: 5744302
    Abstract: The present invention provides various novel covalently modified sapphyrin derivatives and conjugates; polymers including sapphyrin or derivatives thereof; and chromatographic supports including sapphyrins and other expanded porphyrins and derivatives thereof. Disclosed are water soluble sapphyrins, including polyhydroxysapphyrins and sapphyrin-sugar derivatives; sapphyrin-metal chelating conjugates; sapphyrin nucleobase conjugates; oligosapphyrins and polysapphyrins, including sapphyrin dimers, trimers, oligomers and higher polymers; and polymer supported expanded porphyrin compositions, including advantageous rubyrin- and sapphyrin-based chromatography columns and electrophoretic supports. Sapphyrin oligomers and polymers and polymer supported expanded porphyrins, such as, e.g.

  • Sapphyrin chelator derivatives
    Patent number: 5530123
    Abstract: The present invention provides various covalently modified sapphyrin derivatives and conjugates, and also, polymers including sapphyrin or derivatives thereof. Disclosed are water soluble sapphyrins, including polyhydroxysapphyrins and sapphyrin-sugar derivatives; sapphyrin-metal chelating conjugates; sapphyrin nucleobase conjugates; and polymer supported sapphyrins. Novel sapphyrin dimers, trimers, oligomers and polymers are also described, which polymers may include repeating units of sapphyrin or sapphyrin derivatives alone, or may further incorporate other units such as nucleobases.
