To understand the responses of self-assembly in mixtures containing zwitterionic amphiphilic chains to high pressure, we introduce a SCF theory in combination with a mol. equation-of-state model for them in a primitive way. The free energy d. for those in the bulk state is first formulated. Its locally equilibrated excess part is then incorporated into Edwards Hamiltonian along with the electrostatic energy contributions to elicit the saddle point approximation to the partition function with proper SCF equations. It is shown that charge-charge correlations enhance self-assembling tendency for the amphiphiles with the opposite charges on one component side, as the medium dielec. constant εr decreases. Those with the opposite charges at the two chain ends respond in a more complicated way to εr. Densification by applied pressure strengthens the self-assembly for both at a moderate εr, similar to typical phospholipids, but pressure effects are strongly dependent on the position of charges along the chains at a lower εr. It is argued that the manipulation of the dielec. environment and disparity in component dispersion interactions can yield useful materials exhibiting various types of baroresponsivity or thermoresponsivity with re-entrant self-assembly. This study involved multiple reactions and reactants, such as (2R)-3-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)propane-1,2-diyl dipalmitate (cas: 923-61-5HPLC of Formula: 923-61-5).
(2R)-3-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)propane-1,2-diyl dipalmitate (cas: 923-61-5) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.HPLC of Formula: 923-61-5
