Determination of diffusion data and solvodynamic diameters of nonavalent conjugates 12, 17, and 21 by diffusion NMR experiments.

Entry	Compound	D [× 10−10 m2s−1]a,b,c	Solvodynamic diameter [ds, nm]d
1	12	1.33	3.0 (2.9)
2	17	1.62	2.5 (2.3)
3	21	1.17	3.4 (2.9)

^aSee general procedures and Supporting Information File 1 for extraction of the diffusion rate and calibration of the gradient strength. D was determined from the decay of the H-5 resonance (δ = 2.98 ppm). ^bViscosity of D₂O at 25 °C: ηD₂O = 1.097 × 10⁻³ Pa s. ^cThe error associated with the measurement was estimated from repeated calculations of the diffusion coefficients to be below 10%. ^dResults in parentheses correspond to the average value calculated from the decays of 4 or 5 different proton signals.
