a Reaction scheme. b Ultraviolet/visible/near-infrared (UV/vis/NIR) titration of 1 with MB (CH2Cl2, [1] = 1.5 × 10–5 M, r.t.). c Two-dimensional nucleus-independent chemical shifts (2D NICS) grid of dication (12+). d NICS scan relative to y-axis. e NICS scan values relative to z-axis. f ORTEP drawing of 12+ (30% level of probability for thermal ellipsoids; gray, carbon; red, oxygen; light green, chlorine; antimony, purple). Hydrogen atoms are omitted for clarity. Source data are available as a Source data file.
