Carborane-thiol protected copper nanoclusters: stimuli-responsive materials with tunable phosphorescence.

ABSTRACT: Atomically precise nanomaterials with tunable solid-state luminescence attract global interest. In this work, we present a new class of thermally stable isostructural tetranuclear copper nanoclusters (NCs), shortly Cu₄@oCBT, Cu₄@mCBT and Cu₄@ICBT, protected by nearly isomeric carborane thiols: ortho-carborane-9-thiol, meta-carborane-9-thiol and ortho-carborane 12-iodo 9-thiol, respectively. They have a square planar Cu₄ core and a butterfly-shaped Cu₄S₄ staple, which is appended with four respective carboranes. For Cu₄@ICBT, strain generated by the bulky iodine substituents on the carboranes makes the Cu₄S₄ staple flatter in comparison to other clusters. High-resolution e
