Herein we report on the intercalation of polyaniline, poly(2-ethylaniline), and poly(2-propylaniline) into graphite oxide. This was achieved by taking advantage of the exfoliation/reconstruction properties of the layered host. The resulting intercalates were characterized by powder X-ray diffraction...

In this paper we report on the synthesis and characterization of a few alkyl substituted polyanilines into VOPO4. This was achieved by treating the monomers with the highly oxidizing host VOPO4 center dot 2H(2)O. The monomers polymerize and simultaneously insert in between the layers of the host sys...

Polyaniline, poly(ethylene oxide), poly(propylene glycol), poly(vinylpyrrolidinone), methyl cellulose, polyethylenimine, polyethylene, and Nylon-6, were encapsulated into MoS2. Electrical conductivity and thermoelectric power measurements of pressed pellets of (PEO)(0.92)MoS2 and (Polyaniline)(0.35)...

In this paper we report on the insertion of polypyrrole into layered graphite oxide. This was achieved by using the exfoliating and re-stacking properties of the host. The resulting intercalated product was characterized by powder X-ray diffraction, FT-IR spectroscopy, thermogravimetric analysis and...

Intercalation compounds of polyethylene oxide, polyvinylpyrrolidone, methyl cellulose, poly[oxymethylene-(oxyethylene)] and poly[oligo(ethylene glycol oxalate)] into graphite oxide (GO) have been synthesized. The forces of attraction between the polymers and GO are primarily dipole?dipole and/or hyd...

We report on the synthesis and characterization of a series of halo-substituted polyanilines into VOPO4·2H2O. Treatment of the corresponding monomers with the highly oxidizing host VOPO4·2H2O resulted in in situ intercalation/polymerization. The resulting intercalated nanocomposites were character...

Polyaniline (PANI), poly(N-methyl aniline) (PMA), poly(ethyl aniline) (PEA) and poly(propyl aniline) (PPA) were synthesized in their salt form, and then characterized by FT-IR spectroscopy and charge transport measurements. The solubility of the polymers was tested in a variety of solvents and N-met...

Polyaniline, poly( N-methyl aniline), poly(2-ethyl aniline) and poly(2-propyl aniline) were intercalated into layered molybdenum diselenide by using the exfoliation/restacking property of LiMoSe. MoSe was reacted with n-butyllithium to form LiMoSe. The LiMoSe was exfoliated in N-methylformamide (NMF...

In this paper we report on the electrical characterization of conductive polyaniline and its derivatives. Conductivity measurements were also performed on the intercalated phases formed by the encapsulation of the polymers into layered molybdenum disulfide. These measurements were performed using th...

Intercalation compounds of pyrene and 8-anilino-1-naphthalenesulfonic acid into MoS2 have been synthesized and characterized. This was achieved by using the exfoliation/re-stacking properties of LiMoS2. The degree of intercalation was found to be dependent on the amount of guest species used, the re...

Multifunctional macromolecules continue to attract attention. Here, three generations of a new family of bifunctional organoiron dendrimers are reported, which are synthesized from a redox-active organoiron complex, η6-dichlorobenzene-η5-cyclopentadienyl-iron(II). The facile chemistry of the compl...

Poly(ethylene glycol) functionalized with an amino group (PEG-amine) was synthesized and characterized by proton NMR and FTIR spectroscopy. The polymer was complexed with lithium triflate (LiOTf) in varying ratios, and it was found that the composition (PEG-amine)8.0LiOTf exhibited a maximum ionic c...
