Charge transfer enhanced annihilation leading to deterministic single photon emission in rigid perylene end-capped polyphenylenes

摘要

Two new peryleneimide end-capped polyphenylenes are shown to be deterministic single photon sources in PMMA films due to efficient annihilation between charge transfer states.The synthesis and photophysical characterisation of conjugated organic oligomers and polymers have attracted much attention in recent years due to their potential for use as active materials in OLEDs,photovoltaic devices,plastic lasers and field effect transistors.
