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...

Nanocomposites containing ionically-conductive polymers are of interest due to potential applications as solid electrolytes for lithium–ion batteries. This paper reports intercalation of varying mole ratios of poly[oxy-methylene-(oxyethylene)] into lithium hectorite. The resulting nanocomposites w...

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...

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...

MoSe2 has been encapsulated with a variety of guest species. This was achieved by first treating the MoSe2 with an excess of n-BuLi to form the lithiated phase of MoSe2 (LixMoSe2). The LixMoSe2 exfoliates readily in water or NMF to yield single layers of MoSe2. Addition of solutions of polymers, org...

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...

The article presents the results of an experiment which synthesized high molecular weight random copolymers from copolymers of benzophenonetetracarboxylic dianhydride (BTDA), TDA, pyromellitic dianhydride and diaminodiphenyl sulfone. The copolymers underwent chemical imidisation using pyridine as ca...

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...
