Carbon nanothreads, which are one-dimensional sp3-rich polymers, combine high tensile strength with flexibility owing to subnanometer widths and diamond-like cores. These extended carbon solids are constructed through pressure-induced polymerization of sp2 molecules such as benzene. Whereas a few examples of carbon nanothreads have been reported, the need for high onset pressures (≥17 GPa) to synthesize them precludes scalability and limits scope. Herein, we report the scalable synthesis of carbon nanothreads based on molecular furan, which can be achieved through ambient temperature pressure-induced polymerization with an onset reaction pressure of only 10 GPa due to its lessened aromaticity relative to other molecular precursors. When slowly compressed to 15 GPa and gradually decompressed to 1.5 GPa, a sharp 6-fold diffraction pattern is observed in situ, indicating a well-ordered crystalline material formed from liquid furan. Single-crystal X-ray diffraction (XRD) of the reaction product exhibits three distinct d-spacings from 4.75 to 4.9 Å, whose size, angular spacing, and degree of anisotropy are consistent with our atomistic simulations for crystals of furan nanothreads. Further evidence for polymerization was obtained by powder XRD, Raman/IR spectroscopy, and mass spectrometry. Comparison of the IR spectra with computed vibrational modes provides provisional identification of spectral features characteristic of specific nanothread structures, namely syn, anti, and syn/anti configurations. Mass spectrometry suggests that molecular weights of at least 6 kDa are possible. Furan therefore presents a strategic entry toward scalable carbon nanothreads.

“…Nanothreads therefore collectively function as both nanomaterials and chemically versatile hydrocarbon molecules. These materials are predicted to uniquely combine lightweight and high tensile strength/stiffness with elasticity. − In addition, arrays of narrow, stiff, and straight nanothreads exhibit promise for advanced mechanical and thermal properties as bulk materials, useful in a diverse range of applications. − …”

Nanoarchitecture through Strained Molecules: Cubane-Derived Scaffolds and the Smallest Carbon Nanothreads

et al. 2020

Relative to the rich library of small-molecule organics, few examples of ordered extended (i.e., nonmolecular) hydrocarbon networks are known. In particular, sp 3 bonded, diamond-like materials represent appealing targets because of their desirable mechanical, thermal, and optical properties. While many covalent organic frameworks (COFs)extended, covalently bonded, and porous structureshave been realized through molecular architecture with exceptional control, the design and synthesis of dense, covalent extended solids has been a longstanding challenge. Here we report the preparation of a sp 3 -bonded, low-dimensional hydrocarbon synthesized via high-pressure, solid-state diradical polymerization of cubane (C 8 H 8 ), which is a saturated, but immensely strained, cage-like molecule. Experimental measurements show that the obtained product is crystalline with three-dimensional order that appears to largely preserve the basic structural topology of the cubane molecular precursor and exhibits high hardness (comparable to fused quartz) and thermal stability up to 300 °C. Among the plausible theoretical candidate structures, one-dimensional carbon scaffolds comprising six-and four-membered rings that pack within a pseudosquare lattice provide the best agreement with experimental data. These diamond-like molecular rods with extraordinarily small thickness are among the smallest members in the carbon nanothread family, and calculations indicate one of the stiffest one-dimensional systems known. These results present opportunities for the synthesis of purely sp 3 -bonded extended solids formed through the strain release of saturated molecules, as opposed to only unsaturated precursors.

“…[18][19][20][21][22][23][24] As the backbones of nanothreads extend in only one direction, these ultrathin carbon materials are predicted to marry the superlative physical properties of diamond with the flexibility of traditional polymers. [25][26][27][28][29][30] The chemical composition of nanothreads can be precisely controlled through careful selection of small molecule precursors (e.g., benzene, 17,31 pyridine, 32 pyridazine 23 ), giving them potential advantages over comparable nanomaterials (e.g., nanotubes). Therefore, the possible applications of nanothreads are diverse, including novel energy storage and advanced structural materials.…”

Synthesis and Post‐Processing of Chemically Homogeneous Nanothreads from 2,5‐Furandicarboxylic Acid**

Solid-state synthesis represents an alternative to solution-phase chemistry that can provide routes to materials typically unobtainable by conventional methods. However, multiple competing reaction pathways under high-pressure conditions makes the targeted synthesis of chemically homogeneous systems a challenge. Nanothreads, onedimensional diamondoid polymers formed through the compression of aromatic hydrocarbons present a unique opportunity to carry out high pressure reactions in a controlled and predictable manner. We hypothesize that through careful consideration of molecular stacking and intermolecular forces (e.g., H-bonding), it is possible to form chemically homogeneous nanothreads that retain precisely located chemical functionality. Herein, we report the scalable solidstate polymerization of 2,5-furandicarboxylic acid through sequential [4 + 2] Diels Alder cycloaddition reactions. The resulting nanothread product is decorated with a high density of pendant carboxylate groups, presenting new opportunities for post-synthetic processing and functional applications. Transition metal coordination is demonstrated for the functionalized threads, representing proof-of-concept for the utilization of nanothreads as independent synthons and the possibility for novel, extended multidimensional networks.
