Background:

Carbon nanothreads (CNThs) are 1D nanomaterials with predicted strength and flexibility.
Existing CNTh synthesis methods often result in non-uniform structures, posing a significant challenge.

Purpose of the Study:

To develop a method for synthesizing structure-specific carbon nanothreads.
To investigate the polymerization mechanism of 1,2,3-trifluorobenzene under high pressure.

Main Methods:

Utilizing 1,2,3-trifluorobenzene (1,2,3-TFB) as a precursor due to its strong dipole.
Applying a pressure of 20.1 GPa to induce polymerization.
Analyzing the resulting nanostructure and its properties.

Main Results:

Successfully synthesized a carbon nanothread with a highly ordered "zipper polymer" structure.
Observed anti-parallel stacking and selective [4+2] polymerization of 1,2,3-TFB molecules.
The resulting CNTh exhibited high hydrophobicity with a contact angle of 124.6°.

Conclusions:

The study demonstrates a novel approach for precise, atom-level synthesis of CNThs.
Fluorine substitution in the precursor plays a crucial role in reaction selectivity and structural ordering.
The findings provide new insights into the controlled fabrication of 1D nanomaterials.
