Fig. 13. Electrodeposition of PANi in N-F solution (NH4F, 2.35 HF) 0.02 M aniline, by potential sweeping 20 mV s 1 from — 0.2 V to 1.0 V. Reproduced from [182].

Poly(aniline) films were prepared electrochemically on a Pt electrode potentiostatically at 0.85 V vs Ag/AgCl for 5 s from a 1 M aniline in 1 M LiClC>4/CH3CN solution. The films were a faint blue-green color. Thicker films were formed at greater potentials. Even the very... 

Prepare a solution of 0.01 M aniline+O.lM HC1. Assemble a three-electrode cell by using the polished GC disk electrode as working electrode, a bare GC rod as auxiliary electrode and a Ag/AgCl/3M KC1 as reference electrode. Deaerate the cell solution (0.01 M aniline+0.1M HC1) by nitrogen (or argon) bubbling for ca. 

Firstly prepare a solution of 0.1 M aniline in acetate buffer, pH 5.0 (0.4 M sodium acetate, 0.4M acetic acid and 0.4M sodium chloride). Also prepare a solution of acetylcholinesterase (100 U ml-1) in distilled water.

Poly(m-aniline) has also been prepared by palladium-catalyzed condensation of 1,3-dibromobenzene and 1,3-phenylene diamine by two different research groups (Eq. (39)) [170,171]. In this case, reactions using BINAP as ligand gave the highest molecular weights. Kanbara has reported Mw and Mn values in formamide solvent of 42400 and 20100. Meyer et al. have carefiilly analyzed the products of these reactions, and their results cast doubt on the molecular weight data obtained by Kanbara,...

Hartwig has reported a DPPF/Pd-catalyzed C-N coupling reaction between a diarylamine and an aryl nonaflate, Eq. (63) [64bj. The coupling below proceeded in 95 -100% yield (NMR) and was used in a strategy to prepare oligo(m-aniline) compounds. 

Louie and Hartwig described an application of the DPPF/Pd-catalyst toward the synthesis of oligo(m-anilines). The diarylamine monomer was prepared using this protocol in quantitative yield, Eq. (86) [64b]. Goodson and Hartwig have extended the method to synthesize other monomers for the preparation of poly(N-arylanilines) [54 c].
