Aggregation enhanced pure violet emission of a spiral meta-polyfluorene by supramolecular control of excimer formation

Abstract

In π-conjugated optoelectronic functional materials, the excimer in the aggregate state drew much attention because of undesired low energy emission and fluorescence quenching. We report enhanced pure violet emission in meta-polyfluorene by restrained excimer formation in double-helix-like interchain entangled aggregates. It will be beneficial for optoelectric application of conjugated polymers, especially in the processing of film fabrication for high efficiency devices.
