title: A G-octamer scaffold via self-assembly of a guanosine-based Au(I) isonitrile complex for Au(I)-Au(I) interaction.
abstract: A guanosine-based Au(I) isonitrile complex was demonstrated to serve as the reliable scaffold via self-assembly, wherein the quartet and octamer were formed in the absence and presence of a potassium ion, respectively, exhibiting a switchable emission based on Au(I)-Au(I) interaction.
