    摘要： A novel imidazolinium salt is prepared by (1) reacting N-aminoalkyl-imidazoline, N-hydroxyalkyl-imidazoline, or N-substituted-imidazoline with an .alpha.,.beta.-unsaturated ester of a carboxylic acid, (2) reacting the resulting ester imidazoline with a primary or secondary amine and (3) quaternizing the resulting amido imidazoline product by reacting it with an alkylating agent. This imidazolinium salt is useful as a fabric softening agent.

    摘要： Novel N-(haloalkyl)sulfonyl imides represented by the formula ##STR1## are prepared by the reaction of a 2-alkyl- or 2-aryl-oxazoline or oxazine with an arylene or alkane sulfonyl halide. In the formula for the novel sulfonyl imide, R.sub.1 and R.sub.2 are each independently C.sub.1 -C.sub.20 aryl, alkaryl or alkyl groups; R.sub.3, R.sub.4 and R.sub.5 are each hydrogen or methyl groups; n is the integer 0 or 1 and X is a chloro, bromo or iodo group. These novel sulfonyl imides are particularly useful in the preparation of N-(2-chloroethyl)- and N-(3-chloropropyl)sulfonamides.

    摘要： This invention provides a cost effective process and new Janus dendrimers where at least two dendrons are attached at the core (with or without a connector group) and where at least two of the dendrons have different functionality. Preferred are those Janus dendrimers where at least one dendron is a PEHAM dendron. Thus these Janus dendrimers are heterobifunctional in character and use unique ligation chemistry with single site functional dendrons, di-dendrons and multi-dendrons. Also included are Janus dendrons which may be used as intermediates to make the Janus dendrimers or to further react with another reactive moiety. These Janus dendrimers can provide several new dendrimer moieties, namely: combinatorial libraries of bifunctional structures; combined target director and signaling dendrimers; specific targeting entities for diagnostic and therapeutic applications, such as for example targeted MRI agents, targeted radionuclide delivery for diseases such as cancer, and targeted photosensitive or radiowave sensitive agents.

    摘要： In the present invention, an inorganic reactant is, or reactants are, localized with respect to a dendritic polymer by physical constraint within or by a non-covalent conjugation to the dendritic polymer. The localized inorganic reactant or reactants is/are subsequently transformed to form a reaction product which is immobilized with respect to the dendritic polymer. This immobilization occurs on a nanoscopic scale as a consequence of the combined effects of structural, chemical and physical changes without having covalent bonds between the product(s) and the dendritic container and results in new compositions of matter called dendritic nanocomposites. The resulting nanocomposite material can be used to produce revolutionary products such as water soluble elemental metals, with specific applications including magnetic resonance imaging, catalytic, magnetic, optical, photolytic and electroactive applications.

    摘要： An electrically conductive polymer is comprised of the reaction product of a dendrimer and an electrophoric compound which exhibits .pi.-stacking upon reduction. The reaction product which is a peripherally modified dendrimer is formed and reduced, either chemically or electrochemically, in a polar solvent. The reduced electrophoric moieties aggregate (form .pi.-stacks) to form electrically conductive pathways. The reduced peripherally modified dendrimers of the invention can be cast into films and other solid forms to provide flexible electrical conductors and semiconductors. The conductive polymers of the invention exhibit electrical conductivities comparable to that of doped polyacetalene, but are oxygen and moisture stable.
