Au₇₆(SC₆H₄-<i>p</i>-CH₃)₄₂ Square Quantum Platelet: One-Dimensional Growth of Quantum Rods Turns 90 Degrees.

ABSTRACT: The growth pattern of atomically precise nanoclusters (NCs) is of fundamental interest, and the structural effect on their photoluminescence (PL) is important owing to their PL in the second near-infrared (NIR-II) range (900-1700 nm optoelectronically or 1000-1700 nm biologically) that holds great promise for optoelectronic and biomedical applications. Because of the small energy gaps required for NIR-II emission, the PL performance of NIR-II luminophores is largely limited by nonradiative processes. In this work, we discovered a Au₇₆(p-MBT)₄₂ (Au₇₆) (p-MBTH = p-methylbenzenethiol) nanocluster featuring a face-centered cubic (fcc) core in a square shape (edge length: 1 nm). This square quantum platelet can be viewed as a s
