Reaction Parameter Reaction ParameterIn this work, we examine the FeCl3 -initiated oxidative polymerization method and In this function, we examine the FeCl3-initiated oxidative polymerization approach and also the effect of the order of reagent addition around the molecular weight and degree of polythe influence from the order of reagent addition on the molecular weight and degree of merization of 3-hexylthiophene, an alkyl-substituted PEDOT, and an alkoxy-substituted polymerization of 3-hexylthiophene, an alkyl-substituted PEDOT, and an alkoxy-substipolythiophene. Amongst the numerous studies around the oxidative polymerization reaction, the tuted polythiophene. Amongst the numerous research around the oxidative polymerization reaction, order of addition of reagents is hardly ever regarded. The reaction is often performed usthe order of addition of reagents is hardly ever deemed. The reaction is usually performed making use of ing what we term “standard” or “reverse” order of addition (Figure two). Under common what we term “standard” or “reverse” order of addition (Figure 2). Below regular conconditions, the oxidant is gradually added towards the monomer. Beneath reverse circumstances, the ditions, the oxidant is gradually added for the monomer. Beneath reverse situations, the oppoopposite occurs. The original publication by Sugimoto et al. [11] describes polymerization internet site happens. The original publication by Sugimoto et al. [11] describes polymerization of 3of 3-hexylthiophene beneath reverse addition situations, as well as the bulk of other studies are hexylthiophene beneath reverse addition situations, as well as the bulk of other research are carcarried out in this fashion [169,26,31,368,40,435]. ried out within this style [169,26,31,368,40,435].Figure 2.
