Poly(phenylene sulfide–phenyleneamine–phenyleneamine) (PPSAA)—a soluble model for polyaniline

Poly(phenylene sulfide)

“…49 This behavior is in contrast to PPSA, where the molecular weights generally increase with increasing acid strength. In the presence of strong acids, the nitrogen is oxidized to form a −N= structure.…”

“…The process is shown in Figure 5.7. 49 The polymerization is performed by treating the monomer with methanesulfonic acid for 24 h at room temperature. 49 The polymerization is performed by treating the monomer with methanesulfonic acid for 24 h at room temperature.…”

Spatial Extent of the Singlet and Triplet Excitons in Luminescent Angular‐Shaped Transition‐Metal Diynes and Polyynes Comprising Non‐π‐Conjugated Group 16 Main Group Elements

“…In contrast to the body of work on luminescent metallaynes with the p-electron conjugated unit, there are no reports of similar systems possessing Group 16 chalcogen units in the backbone. There are also numerous reports on the syntheses and applications of purely organic polymeric systems of arylene ether, sulfide, sulfoxide and sulfone in the literature, [27][28][29][30] but little research on rigid-rod chalcogen-derived metallaynes and their corresponding polyynes has been carried out. To get a deeper insight, it is important to develop synthetic strategies leading to novel conjugated polymers with non-p-conjugated Group 16 heteroatoms in the polymer chains.…”

Design, synthesis and characterization of novel nitrogen- and sulfur-containing polymers with well-defined conjugated length

“…8 This synthetic concept was further extended to the design and synthesis of poly (phenylene sulfide-phenyleneamine-phenyleneamine) (PPSAA) by Mu ¨llen. 9 However, two alternating conjugated polymers (PPSA and PPSAA) could not be doped to be conductive by protonic acids, due to the too short iminophenylene segment in their repeat unit.…”
