An interfacial polymerization was used to fabricate dodecybenzenesulfonic acid (DBSA)-doped polyaniline (DBSA-PANI) nanorods with diameter range from 40 nm to 1 lm. The molar ratio of aniline to ammonium peroxydisulfate (APS), the concentrations of DBSA and reaction temperature had an effect on the morphology and size of products. It was found that lower concentration of DBSA and lower temperature will be helpful to the formation of rod-like PANI nanostructures with a relative small diameter. UV-vis and FTIR measurements were used to characterize the chemical structure of the obtained samples.

Electrochemical properties of well-defined molecular structured polyamide with amine-capped aniline pentamer in the main chain and conventional polyaniline were investigated and discussed. CV results suggest that the synthesized polyamide shows a relatively complicated redox process than conventional polyaniline during potential cycling. Differences in ESI characterization revealed that the synthesized polyamide exhibits higher electronic conductivity and lower resistance than the conventional polyaniline. The analysis of molecular configuration based upon the quantum chemistry calculation reveal that the difference in electrochemical activity and conductivity should be ascribed to the influence of system energy, skeleton conjugation, and the Fermi energy of the bipolaron model in the polymer molecules.

Using multiethylenemultiamine to direct the crystallization of inorganic frameworks through multipoint hydrogen bonds, two new oxovanadium borophosphates, denoted VBP-J1 and VBP-J2, have been synthesized by hydrothermal methods as well as under reflux conditions. Powder X-ray diffraction patterns indicate that VBP-J1 and VBP-J2 are structural analogues. Structure determinations show that both VBP-J1, [H3NC2H4NH2C2H4NH2C2H4NH3]4H[NH4(VO)12{O3POB(O)2OPO3}6]·14H2O and VBP-J2, [H3NC2H4NH2C2H4NH2C2H4NH3]4H[K(VO)12{O3POB(O)2OPO3}6]·16H2O crystallize in the orthorhombic space group Pbca with crystal data: a = 21.454(11) Å, b = 16.315(6) Å, c = 29.651(12) Å, α = β = γ = 90°, V = 10378(8) Å3, Z = 4 for VBP-J1 and a = 21.537(2) Å, b = 16.2667(13) Å, c = 29.717(4) Å, α = β = γ = 90°, V = 10410.8(18) Å3, Z = 4 for VBP-J2. VBP-J1 and VBP-J2 are constructed by edge-sharing {V2O10} binuclear unit and {BP2O10} trimer to form interesting 12-member ring crown-shaped clusters with NH4 + and K+ cations encapsulated in the clusters. The ring diameters are 5.873 × 5.412 × 5.561 Å for VBP-J1 and 5.758 × 5.421 × 5.236 Å for VBP-J2. An extended network of multiple hydrogen bonds among anions, cations, and water molecules links the structure in three dimensions.
