“…The template-based organization of buckminsterfullerene C 60 in one-dimensional array was achieved by using various approaches: fullerene incorporation (by wet chemistry) into the channels of zeolites [83], surface adsorption on the monolayers of the Au chain structures acting as adsorption templates [84], or C 60 trapping in situ during carbon nanotube formation, following pulsed laser vaporization of graphite [85]. DNA could be also used as a framework for the assembly of fullerene nanomaterials through electrostatic interactions with the phosphate groups along the DNA backbone [86].…”

The large interest in nanostructures results from their numerous potential applications in various areas such as materials and biomedical sciences, electronics, optics, magnetism, energy storage, and electrochemistry. Ultrasmall building blocks have been found to exhibit a broad range of enhanced mechanical, optical, magnetic, and electronic properties compared to coarser-grained matter of the same chemical composition. In this paper various template techniques suitable for nanotechnology applications with emphasis on characterization of created arrays of tailored nanomaterials have been reviewed. These methods involve the fabrication of the desired material within the pores or channels of a nanoporous template. Track-etch membranes, porous alumina, and other nanoporous structures have been characterized as templates. They have been used to prepare nanometer-sized fibrils, rods, and tubules of conductive polymers, metals, semiconductors, carbons, and other solid matter. Electrochemical and electroless depositions, chemical polymerization, sol-gel deposition, and chemical vapour deposition have been presented as major template synthetic strategies. In particular, the template-based synthesis of carbon nanotubes has been demonstrated as this is the most promising class of new carbon-based materials for electronic and optic nanodevices as well as reinforcement nanocomposites. PACS: 61.46.+w; 61.48.+c; 61.82.RxIn 1959 Richard Feynman, the future Nobel Laureate, suggested in his famous lecture, entitled "There's Plenty of Room at the Bottom", a variety of tests that might be achieved at very small scales. Three decades later Feynman's vision has become the greatest scientific frontier of the century. It opened a new field of "Nanostructures" having dimensions of about 10 to 1000 Å, a size that is small by engineering standards, common by biological standards, and large to chemists.The central thesis of nanotechnology is that almost any chemically stable structure that can be specified can actually be built. Nature has plenty of proof that nanotechnology works, from the liposomes in cells that manufacture proteins atom by atom, to the chloroplasts of plants that turn sunlight, carbon dioxide, and water into copies of themselves. Since biological machines exist, and work, and since biology follows the same laws of physics and chemistry applied by engineers, there's no question the nanostructural machines will work. Scientists have to figure out, however, how to build them.Of particular significance is the size dependence of many properties in nanomaterials, for example, an enhancement in the strength and hardness of solids; the possibility of modifications of their electrical properties by control of the arrangement within the constituent nanoclusters and of their assembly; the control of chemical reactivity by the attachment of functional side-groups; the control of optical properties by variation of the size and microstructure of the nanoclusters; the possibility of creating nanostructures of metastable phases with no...

“…Nanoscale templating was also carried out to produce 1-and 2-dimensional elongated carbon nanostructures using Au/Ni (110) [84] and layered cobalt [66] as patterned catalysts. The interchain separation of obtained nanostructures was dictated by the surface modification of adsorption templates.…”

Templated Growth of Metal–Organic Coordination Chains at Surfaces

et al. 2005

Metal-organic coordination networks (MOCNs) formed by coordination bonding between metallic centers and organic ligands can be efficiently engineered to exhibit specific magnetic, electronic, or catalytic properties. [1][2][3][4][5][6] Instead of depositing prefabricated MOCNs onto surfaces, it has been recently shown that two dimensional (2D) MOCNs can be directly grown at metal surfaces in ultra high vacuum (UHV), thus creating highly regular 2D networks of metal atoms. [7][8][9][10][11][12] These grids have been pointed out to be potentially relevant for devices involving sensing, switching, and information storage. [13,14] We show here that this approach offers the additional advantage to predefine the MOCN geometry by using the substrate as template to direct the formation of novel 1D metal-organic coordination chains (MOCCs).The templating role of substrates is well known in the field of surface epitaxial growth. [15][16][17][18][19] Among the highly anisotropic substrates, the Cu(110) surface is one of the most common (Figure 1a and b). In order to evidence its strong 1D templating effect on organic molecules, a ligand with a triangular symmetry was selected: 1,3,5-benzenetricarboxylic acid (trimesic acid, TMA, Figure 1c). In fact, the 3-fold rotation symmetry supports the formation of hexagonal 2D and 3D architectures, [20][21][22] therefore strongly disfavoring the linear geometry. On the isotropic Cu(100) surface, TMA forms 0D carboxylate complexes and 2D networks. [9,10] The UHV deposition of TMA on Cu(110) at 300 K results in the formation of 1D chains along the 110 direction, as observed by STM. This deposition temperature is high enough to * * The authors wish to acknowledge Nian Lin, Magalí Lingenfelder, Alexander Schneider and Giacinto Scoles for fruitful discussions, HPC-EUROPA (project #506079) and INFM Progetto Calcolo Parallelo for computer resources.

“…However, quasi-1D C 60 nanostructures have been rarely realized experimentally due to their highly anisotropic configuration. A few previously reported experimental results include C 60 peapods by embedding C 60 molecules in carbon nanotubes, 1D C 60 structures aligned along step edges on vicinal surfaces of metal single crystals, and C 60 chains on self-assembled molecular layers 16 17 18 19 20 21 22 23 24 25 26 . For CVD graphene, periodically linear rippled structures have been previously observed on various growth substrates 27 28 .…”

We report the preparation of novel quasi-one-dimensional (quasi-1D) C60 nanostructures on rippled graphene. Through careful control of the subtle balance between the linear periodic potential of rippled graphene and the C60 surface mobility, we demonstrate that C60 molecules can be arranged into a quasi-1D C60 chain structure with widths of two to three molecules. At a higher annealing temperature, the quasi-1D chain structure transitions to a more compact hexagonal close packed quasi-1D stripe structure. This first experimental realization of quasi-1D C60 structures on graphene may pave a way for fabricating new C60/graphene hybrid structures for future applications in electronics, spintronics and quantum information.
