Popis: | A new synthetic route to polytriarylamines by microwave-assisted palladium-catalysed amination between 2,4-dimethylaniline and 4,4'-dibromobiphenyl is reported. The use of microwave heating significantly reduces the polymerisation time from days to around five minutes when conducted at 100°C. However, prolonged microwave irradiation (20 min) can cause chain degradation of these polymers. Reactive amino and bromo end-groups can be removed by sequential reaction with 4-bromoanisole and diethylamine to generate polytriarylamines that are suitable for the fabrication of organic electronic devices. |
