Alcohol-induced decomposition of Olmstead's crystalline Ag(i)–fullerene heteronanostructure yields ‘bucky cubes’

Functional Nanomaterials Prepared by Nanoarchitectonics-Based Supramolecular Assembly

“…Shrestha et al reported studies on nanofabrication involving highly crystalline cubic-shaped crystals of a C 60 -AgNO 3 organometallic heteronanostructure [19]. These crystals could be converted into uniquely structured formations of welloriented assemblies of C 60 nanoneedles, known as bucky cubes ( Fig.…”

Femtosecond‐Laser Direct Writing of Metallic Micro/Nanostructures: From Fabrication Strategies to Future Applications

“…In near‐field optics (Figure g), the FsLDW of metallic micro/nanostructures also plays a very important role. The SERS technique has attracted much attention because it can directly provide fingerprint information on various target molecules, and thus allows the highly sensitive detection of analytes at very low concentrations, even at the single‐molecule level . The enhancement of the electromagnetic field for SERS relies heavily on the LSPR derived from the metal nanostructures .…”

Self-Assembled Fullerene Nanostructures

“…These 3D flower-shaped C 60 crystals have hexagonal close packed structure and show intense photo luminescence PL compared to pristine C 60 54 . Our group very recently succeeded to fabricate highly crystalline cube-shaped crystals of C 60 -fullerene-Ag I organometallic heteronanostructure C 60 AgNO 3 5 , which undergoes irreversible structural rearrangement upon exposure to low molecular weight aliphatic alcohols in particular 1-butanol yielding a uniquely structured formation of welloriented C 60 nano/microcrystals bucky cubes 35 . The mechanism of rearrangement represents a supramolecular analogue of topotactic processes more commonly associated with some purely inorganic materials, such as maghematite, where chemical changes can occur with addition or , undergoes a supertopotactic transformation from a crystalline organometallic complex to well-ordered cube-shaped arrays of needle-like C 60 crystals which reflect the original cubic crystal morphology an internal structure.…”

“…Very recently, we extended this method to produce giant microcrystals with macropores at their surfaces and also succeeded in fabricating, for the first time, hexagonal-shaped crystalline fullerene with bimodal pore structures 33,34 . Furthermore, we utilized this method for the unusal formation of 3D highly crystalline cubic-shape crystals of C 60 -fullerene-Ag I organometallic heteronanostructure C 60 AgNO 3 5 , which showed irreversible structural rearrangement upon gentle washing with aliphatic alcohols resulting in the formation of uniquely structured formations of well-oriented C 60 microcrystals 35 .…”
