Two diamine monomers with methyl (CH3TPA) and methoxy (OCH3TPA) group substituents in the para position of the triphenylamine (TPA) moiety were synthesized by nucleophilic aromatic substitution using 4-fluoronitrobenzene with p-toluidine and p-anisidine,

A series of novel aromatic polyamides with pendent 4,4′-dimethoxy- substituted triphenylamine (TPA) units were prepared via the direct phosphorylation polycondensation from a new dicarboxylic acid monomer, N,N-bis(4-carboxyphenyl)-N′,N′-di(4-methoxyphenyl)-1, 4-phenylenediamine (4), and various aromatic diamines. These polyamides were amorphous with good solubility in many organic solvents, such as N-methyl-2-pyrrolidinone (NMP) and N,N-dimethylacetamide (DMAc), and could be solution-cast into flexible polymer films. They had excellent levels of thermal stability associated with their relatively high glass-transition temperatures (233-308 °C). These polymers exhibited strong UV-vis absorption bands at 351-363 nm in NMP solution. Their photoluminescence spectra showed maximum bands around 450-504 nm. The hole-transporting and electrochromic properties are examined by electrochemical and spectroelectrochemical methods. Cyclic voltammograms of the polyamide 6g prepared from the dicarboxylic acid monomer (4) with a structurally similar diamine monomer N,N-bis(4-aminophenyl)-N′, N′-di(4-methoxyphenyl)-1,4-phenylenediamine (5g) exhibited four reversible oxidation redox couples in acetonitrile solution at Eonset = 0.35, E1/2 = 0.64, 0.84, and 0.99 V, respectively. After over 3000 cyclic switches for green color, the films of polyamide 6g still showed excellent continuous cyclic stability of electrochromism.
