1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. Computed Properties of C10H20O5

The author of 《Microfriction correction factor to the Stokes-Einstein equation for small molecules determined by NMR diffusion measurements and hydrodynamic modelling》 were Dvorak, Petr; Soltesova, Maria; Lang, Jan. And the article was published in Molecular Physics in 2019. Computed Properties of C10H20O5 The author mentioned the following in the article:

The Stokes-Einstein relationship relating the self-diffusion coefficient with the size of a diffusing particle (a hydrodynamic radius) breaks down in case of small mols. We present a novel method extending the range of validity of the Stokes-Einstein relationship by means of introducing a mol.-specific microfriction correction factor. This factor equals to 1 in the ordinary form of the Stokes-Einstein formula for ‘stick’ boundary conditions when mols. of solvent are much smaller than the diffusing particle. We have determined the microfriction correction factors for series of small mols. (ranging in size from ethanol to 18-crown-6 ether and tetrakis(trimethylsilyl)silane) in a dilute hexane solution by a concerted use of the NMR diffusion measurements and the mol. hydrodynamic calculations Both of the tested hydrodynamic modeling programs, HydroNMR (Garcia de la Torre et al., J. Magn. Reson. 2000, 147, 138-146) and DiTe (Barone et al., J. Comput. Chem. 2008, 30, 2-13) provided very similar results after initial calibration on a mol. system, which is within the validity range of the Stokes-Einstein relationship (fullerene in hexane solution in this work).
