compound	molecular weight	diffusion coefficient (10⁻⁶ cm²/s)	diameter (nm)
4	21208.46	2.13 ± 0.1^b	6.6 ± 0.2^a
		2.2 ± 0.2^c	6.7 ± 0.3^a
			6.9^d
5	24358.16	1.69 ± 0.2^b	8.1 ± 0.2^a

Calculated from the diffusion coefficient using the Stokes–Einstein equation.

Obtained from PGSE experiments (CD₃COCD₃, 298 K).

Obtained from electrochemical measurements.

Obtained from molecular modeling as the measured distance between the two most separated points of the functional units.
