Cu-catalysed oxidative C-H/C-H coupling polymerisation of benzodiimidazoles: an efficient approach to regioregular polybenzodiimidazoles for blue-emitting materialsElectronic supplementary information (ESI) available. See DOI: 10.1039/c4cc06291d

The Cu-catalysed oxidative C-H/C-H coupling reaction of azoles has been used for the first time to develop polymerisation, which provides an efficient method for the preparation of polybenzodiimidazoles. These polymers exhibit high molecular weights, regioregularity, blue-emitting performance and thermal stability. The Cu-catalysed oxidative C-H/C-H coupling reaction of azoles has been used for the first time to develop polymerisation. The resulting polybenzodiimidazoles exhibit high molecular weights, regioregularity.
