    • The pairs of ortho and meta phenyl protons are not equivalent, and their resonances are split into a pair of multiplets each (assignments were made with a NOESY experiment, see Supporting Information).

    • 1b has a mobility on silica gel that is intermediate between those of the corresponding free-base 1 and the fully zincated adduct 1a. This guarantees that 1b is a real species and not an equimolar mixture of 1 and 1a. The same considerations apply to 2b.

    • The feature at 520 nm in the spectrum of 2a is attributed to a minor (ca. 5%) amount of free-base absorption arising from incomplete Zn insertion.

    • y, θ = 90°. With these figures, the expected exciton splittings (energy differences between the red-shifted x-polarized transition and the blue-shifted y-polarized transition) are calculated to be in a ratio 2.2 for staggered vs planar compounds (see Supporting Information).
