Fused-Ring Carbon Nanothread Synthesized by Pressure-Induced Polymerization of Azulene

sp3-Carbon nanothreads (sp3-CNTh) have attracted broad attention due to their one-dimensional diamond-based structure and predicted excellent mechanical and electrical properties. The quality of CNTh is significantly affected by defects and disorders, and the synthesis of ordered CNTh is still very challenging. Here, we successfully synthesized an orderly stacked fused-ring CNTh from azulene, with an obvious color change from blue to orange. At 1.2 GPa, azulene underwent a phase transition, as identified by in situ spectroscopy and X-ray diffraction (XRD). Above 15 GPa, azulene reacted irreversibly, forming an orderly stacked CNTh, confirmed by XRD and transmission electron microscopy. Solid-state nuclear magnetic resonance of CNTh revealed the presence of both sp2- and sp3-C. Our study reported an orderly stacked fused-ring CNTh and elucidated its formation through a high-pressure chemical reaction of azulene, which gives new insights into the pressure-induced polymerization of aromatics and is of benefit for designing and synthesizing new CNThs.

Abstract

sp3-Carbon nanothreads (sp3-CNTh) have attracted broad attention due to their one-dimensional diamond-based structure and predicted excellent mechanical and electrical properties. The quality of CNTh is significantly affected by defects and disorders, and the synthesis of ordered CNTh is still very challenging. Here, we successfully synthesized an orderly stacked fused-ring CNTh from azulene, with an obvious color change from blue to orange. At 1.2 GPa, azulene underwent a phase transition, as identified by in situ spectroscopy and X-ray diffraction (XRD). Above 15 GPa, azulene reacted irreversibly, forming an orderly stacked CNTh, confirmed by XRD and transmission electron microscopy. Solid-state nuclear magnetic resonance of CNTh revealed the presence of both sp2- and sp3-C. Our study reported an orderly stacked fused-ring CNTh and elucidated its formation through a high-pressure chemical reaction of azulene, which gives new insights into the pressure-induced polymerization of aromatics and is of benefit for designing and synthesizing new CNThs.
