“…The improved synthesis of PHBQS was carried out in a toluene/water cosolvent medium by condensation between hydroquinone and elemental sulfur using NaOH as a catalyst (Scheme ). The polymerization route is based on the catalyzed condensation reaction between phenol and sulfur under alkaline conditions, producing sulfur-bridged oligophenols at elevated temperatures . Although our previously reported synthesis procedure based on this route produced PHBQS in acceptable yields (39%), the method was time-consuming (4 days) and hence unsuitable for large-scale preparation.…”

Cost-effective, simple, and easily reproducible synthesis methods of polymers are of profound significance when it comes to extracting high battery performance metrics from polymeric redox-active materials. This work reports a procedure for the solvothermal synthesis of a poly(hydroquinonyl-benzoquinonyl sulfide) (PHBQS) polymer and the development of its nanostructured composites with multiwalled carbon nanotubes (MWCNTs). Polymers are tested as high-performance cathode materials for Li+ and Mg2+ batteries. In configurations, compared to neat PHBQS, the PHBQS@5%MWCNT cathode exhibits superior electrochemical performance with high active material utilization owing to improved ion/electron transport pathways. Galvanostatic characterization of the PHBQS@5%MWCNT cathode in lithium batteries exhibited peak capacity up to 358 mAh g–1 at a current density of 50 mA g–1 (C/8) and excellent rate performance with a discharge capacity of 236 mAh g–1 maintained even at high current density of 10C. The galvanostatic characterization in Mg batteries reveals more sluggish kinetics with a stable capacity of 200 mAh g–1 at 50 mA g–1.

The reactions of six substituted chlorobenzenes with sulfur were investigated, and the results were compared with the results of earlier investigations in which sodium carbonate also took part in the reactions. The effect of the amount of chlorine and of the different substituents on the reaction mechanism is discussed. The approximate structures of the cross-linked substituted poly(pheny1ene sulfide)s are also given.
