The preparation of the solvents discussed in this work were accomplished by way of a reaction between POCl3 and an excess of alcohol catalyzed by 4-dimethylaminopyridine in dichloromethane (DCM); all reagents were used as received from Sigma Aldrich. The method of preparation of these compounds was derived from reactions reported by Hess, et al. The solvents prepared in this work are shown in Figure . Three symmetrical solvents with different lengths of PEG-substituted side-chains were prepared, with their physical properties listed in Table along with TBP and T i BP.
