  日期：——

  The streptavidin–biotin interaction on a monolayer of a conically shaped dendrimer was investigated by surface plasmon resonance (SPR) spectroscopy and the interaction on the mesospaced surface was found to be as efficient as the one on the mixed monolayers at a lower concentration of immobilized biotin.

• An Improved Synthesis of a Trifurcated Newkome-Type Monomer and Orthogonally Protected Two-Generation Dendrons
  作者：Claudia M. Cardona、Robert E. Gawley

  DOI：10.1021/jo0161678

  日期：2002.2.1

  The one-step synthesis of amino-polyether tritert-butyl ester monomer 2, by condensation of TRIS with tert-butyl acrylate, is reported. The nitrogen of the monomer can be protected with a Cbz group; subsequent removal of the tert-butyl esters with formic acid affords a triacid that is coupled to three monomers to afford an orthogonally protected two-generation, trifurcated polyether-polyamide dendron. The Cbz protecting group may be removed from the second-generation dendron without disturbing the tertbutyl esters of the periphery.
• Self-Association of Protected Newkome-Type Second-Generation Dendrimers at Nanomolar Level Concentrations in Aqueous Solution

  Protected Newkome-type second-generation dendrimers (based on Lin's amine) were synthesized with a pyrene moiety attached to the core. The photophysical property in aqueous solution of the protected dendrimers shows self-association behavior in water. Pyrene excimer emission at 475 nm is observed in water even at very low concentrations of protected dendrimer (ca. 5 x 10(-8) M). This emission band is absent in other solvents even up to a concentration of 10(-5) M. The corresponding unprotected dendrimer does not show the pyrene excimer fluorescence. The amide of pyrene butyric acid with tert-butylamine shows the formation of excimer, albeit with very low intensity. Quenching studies on the dendrimer with hydrophilic quencher iodide anion (I-) reveal that there is significant quenching of fluorescence intensity in the case of N-tert-butyl-4-pyren-1-ylbutyramide as compared to that of the pyrene-attached second-generation protected dendrimer. This shows that the pyrene moiety in the case of the protected dendrimer is significantly shielded from the surrounding.
• Spatially Resolved Derivatization of Solid-Phase-Synthesis Beads with Fluorescent Dendrimers: Creation of Localized Microdomains

  日期：2002.10

  Second and third generation Newkome-type trifurcated dendrimers, containing either a coumarin or dansyl fluorescent probe at the dendrimer core, have been synthesized and attached to ArgoGel (R) solid-phase-synthesis beads. Subsequent reaction with rhodamine dye shows that the dye can penetrate throughout the beads to acylate the remaining sites. Thus, it is possible to achieve a spatially resolved microdomain for library formation at the core of the dendrimer, primarily on the bead's periphery, and a second microdomain suitable for derivatization by other reagents such as encoding tags and fluorescent sensors.
