  Phenalenyl in a Different Role: Catalytic Activation through the Nonbonding Molecular Orbital

  摘要：

  We have demonstrated that the nonbonding molecular orbital (NBMO) of the phenalenyl (PLY) cation can be used as a Lewis acid catalyst for different organic transformations. Detailed computational and spectroscopic studies for the aminolysis reaction of epoxide reveal that this catalysis works through a different mechanism, and the phenalenyl cation activates the amine moiety using its empty NBMO, which triggers the epoxide ring-opening reaction. It has been shown that the energy of the NBMO of PLY cation plays a key role in modulating the catalytic activity. This study establishes that the cationic state of phenalenyl unit is useful not only for construction of the spin memory device by external spin injection using its NBMO, but in addition, the same NBMO can act as an organic Lewis acceptor unit to influence the catalytic outcome of a homogeneous reaction.

• Ethylenically unsaturated monomers for thickener compositions

  New ethylenically unsaturated monomers are provided that can be (co)polymerized to provide a composition and method whereby the same group that is attached to or within the backbone of an associative thickener is reversibly switched between being hydrophilic and hydrophobic in nature. When the group that is attached to or within the backbone is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this group is rendered hydrophobic, the thickener performs its thickening function efficiently. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened. The thickeners are prepared from the novel monomers by an aqueous solution polymerization.

  A polymer composition with blocks of hydrophobes attached to or within the backbone of an associative thickener. The blocks are composed of two or more units of the same or different hydrophobes whereby the hydrophobe is reversibly switched between being hydrophilic and hydrophobic in nature. When the hydrophobe is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this hydrophobe is rendered hydrophobic, the thickener performs its thickening function efficiently, especially in tinted systems. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened.
