Fluorescent Nanowires Self‐Assembled through Host–Guest Interactions in Modified Calcein

Abstract

Selbstorganisierte Nanodrähte (siehe Bild), die in wässriger Lösung aus cyclodextrin‐ und adamantanmodifiziertem Calcein entstehen, werden mit einer Kombination aus Rasterelektronenmikroskopie, Laserrastermikroskopie und Wärmestrom‐Differenzkalorimetrie untersucht, wodurch die Stabilität und Widerstandsfähigkeit dieser Drähte bezüglich ihres Abbaus belegt wird.

Cyclodextrin and Adamantane Host–Guest Interactions of Modified Hyperbranched Poly(ethylene imine) as Mimetics for Biological Membranes

“…The analogous guest polymer 2 was prepared accordingly 24. The cyclodextrin‐ and adamantyl‐functionalized fluorescent dyes 3 and 4 were synthesized by a literature procedure25 in order to study the supramolecular self‐assembly of functionalized PEI with the corresponding dye (Scheme ).…”

Photonic DNA-Chromophore Nanowire Networks: Harnessing Multiple Supramolecular Assembly Modes

“…36–38 In addition, the adamantane moieties were specifically included since the self-assembled quadruplex 2 would then project four adamantane units from each of its two termini. Based on earlier work by our group and others on multivalent host-guest interactions on non-DNA derived supramolecular nanostructures, 39–42 we envisioned that addition of a non-covalently “cross-linking” free-base porphyrin ( 3 ) that presents four PMβ-CD hosts from each face (and has dimensions that closely match the terminal face of a DNA quadruplex) 43 should result in DNA-porphyrin array 4 as a result of repetitive multivalent host-guest interactions.…”
