Chen et al. [24] studied the structure and effect of the side chain length on the doping level of self-doped poly(n-(3 -thienyl)alkanesulfonic acid)s with alkanes of carbon numbers 2, 6 and 10. They suggested that self-doping of poly(n-(3 -thienyl)alkanesulfonic acid)s is dependent on the side chain length (for details see Chapter 1 Section 1.4.3). In subsequent work, Chen et al. reported the irreversible thermal dedoping...

The first water-soluble, electroactive, self-doped sulfonatoalkoxy-substituted PPP, poly[2,5-bis(3-sulfonatopropoxy)-l,4-phenylene-aZf-l,4-phenylene] (55), was synthesized from 1,4-benzenediboronic acid [4612-26-4] (56) and the disodium salt of l,4-dibromo-2,5-bis(3-sulfonatopropoxy)benzene (57) by the homogeneous Suzuki coupling method (130). The polymer purified by dialysis of an aqueous solution was composed exclusively of 1,4-linkages. The abihty to utilize a variety of bis(boronic acids) in this polymerization with sulfonate containing aiyl hahdes will lead to a high degree of structural control of the optoelectronic properties of these water-soluble poljnners. 

The structure of self-doped poly(52-2) was found to involve the polaron and bipolaron with addition of protons on some a-carbons of the rings resulting from a redox process and titration with aqueous sodium hydroxide, and the four basic unit structures were proposed [118]. 

Another class of conducting polymers that has been of interest for charge dissipation in e-beam lithography is that of the water-soluble, self-doped poly thiophenes such as the sulfonated derivatives, which have the general structure depicted here [26,68-70]. The one disad-...
