摘要:
Rosette nanotubes (RNTs) are discrete nanostructures self-assembled from a guanine-cytosine hybrid motif (G Lambda C) under aqueous conditions. These materials have substantial design flexibility and a range of applications, which are partly attributed to their diverse surface functionalization. Given the potential for interesting properties resulting from a metal-RNT construct, here we describe an oxorhenium-functionalized RNT. More specifically, we present the synthesis of a twin G Lambda C motif expressing the mercaptoacetyl triglycine (MAG(3)) ligand. We then examine the chelation reaction of the MAG(3) with ReOCl3(PPh3)(2) and self-assemble the resulting ReO-MAG(3)-G Lambda C conjugate into RNTs under DMSO and aqueous conditions.
