Computer Simulation of Luminophore Solubilization in Reverse Micelles

详细

The solubilization of ionic (sodium naphthalene-2,6-disulfonate) and nonionic (diethyl 2,5-dihydroxyterephthalate) organic luminophores in water–isooctane–NaАОТ (sodium 1,4-bis[(2-ethylhexyl) oxy]-1,4-dioxybutane-2-sulfonate) reverse micelles is simulated by the molecular dynamics method. In a stationary state, the localization of luminophore molecules in a micelle appears to be the same irrespective of their initial positions in the system. The position and orientation of solubilized luminophores relative to a reverse micelle depend on the hydrophobicity and the capability for dissociation of the functional groups of their molecules, the size of the reverse micelle, and the structure of its electrical double layer.
