“…In the 1 H NMR spectra of PTPA (Figure 3), a series of peaks at 6.5-8.2 ppm, corresponding to the protons of the hyperbranched aromatic rings, revealed that PTPA had been synthesized successfully. Although the undesired displacement of nitro groups can occur during the polymerization [53][54][55][56] any related peaks were not observed in the spectrum, indicating there was no side reaction. The infrared spectra of 5 and PTPA, shown in Figure S8, also supported the conclusion of polymerization.…”

We synthesized a new poly(triphenylamine), having a hyperbranched structure, and employed it in lithium-ion batteries as an organic cathode material. Two types of monomers were prepared with hydroxyl groups and nitro leaving groups, activated by a trifluoromethyl substituent, and then polymerized via the nucleophilic aromatic substitution reaction. The reactivity of the monomers differed depending on the number of hydroxyl groups and the A2B type monomer with one hydroxyl group successfully produced poly(triphenylamine). Based on thermal, optical, and electrochemical analyses, a composite poly(triphenylamine) electrode was made. The electrochemical performance investigations confirmed that the lithium-ion batteries, fabricated with the poly(triphenylamine)-based cathodes, had reasonable specific capacity values and stable cycling performance, suggesting the potential of this hyperbranched polymer in cathode materials for lithium-ion batteries.
