Precision Synthesis of a Single Chain Polymorph of a 2D Solid within Single-Walled Carbon Nanotubes.

ABSTRACT: The discovery and synthesis of atomically precise low-dimensional inorganic materials have led to numerous unusual structural motifs and nascent physical properties. However, access to low-dimensional van der Waals (vdW)-bound analogs of bulk crystals is often limited by chemical considerations arising from structural factors like atomic radii, bonding or coordination, and electronegativity. Using single-walled carbon nanotubes (SWCNTs) as confinement templates, we demonstrate the synthesis of a short-wave infrared-absorbing quasi-1D (q-1D) chain polymorph of Sb₂Te₃ ([Sb₄Te₆]_n) that is structurally and electronically distinct from its 2D counterpart. It is found that the q-1D chain polymorph has both three- and five-coordinate Sb atoms
