| Description
| - Polyaniline (PANI) is among the most studied conducting polymers because of its outstanding properties, such as a relatively high conductivity, easy preparation and processing, low cost, and environmental stability.[1] The role of the chemical structures of PANI in their different varieties—from linear structures to phenazines components—has been followed in detail in recent studies[2, 3] using the powerful in situ ESR/UV/Vis/NIR spectroelectrochmistry[4] and in situ FTIR spectroelectrochemistry.[ 5] A further route to vary the chemical structure of PANI is the development of self-doped derivates of PANI which present better solubility,[6] redox activity[7] and conductivity[6, 8] over a wider pH range as compared to PANI. These derivatives contain anionic functional groups which are able to interact with the positively charged nitrogen atoms of the polyaniline chains causing new effects different from those of polymers doped with solution anions. Among the group of self-doped PANI, poly(aniline boronic acid) (PANI-BA)[9] exhibits a unique self-doping mechanism, different from the conventional mechanism for sulfonic acid, carboxylic acid and phosphoric acid substituted polyanilines. The self-doped mechanism of PANIBA is controlled through the formation of four-coordinate boronate species in the presence of Lewis bases including diol moieties such as carbohydrates, vitamins, coenzymes and ribonucleic acids[10] as well as alcohols[11] and fluoride.[12] The anionic tetrahedral boronate ester formation acts as an inner dopant and balances the positive charge on the nitrogen of the polyaniline backbone. This property has been used to facilitate the electrochemical polymerization[13] and the chemical synthesis of water-soluble PANI-BA.[14] In addition, the intermolecular reaction between boronic acid groups and imines in PANI-BA containing fluoride promotes the formation of self-crosslinked PANI-BA with enhanced thermal properties.[15]
