Further progress in research and industry requires efficient monitoring of different analytes (oxygen, pH, carbon dioxide, volatile organic vapors etc.) including unique ones (e.g. coronavirus). Recently discovered organic emitters with long persistent luminescence (LPL) are predictively perfect candidates for new generation of optical sensors. Such prediction is based on the fact that LPL decays are much longer than decays of emission of rare-earth-atom-based phosphorescent emitters used in state-of-art optical sensors. The main idea of the project is development of new organic LPL emitters towards their application in optical sensors. Since organic materials exhibiting LPL are based on solid-state mixtures of exciplex-forming materials, the objective of the project is exciplex-forming electron-donating and electron accepting organic compounds suitable for oxygen LPL probes. New exciplex-forming compounds will be designed, synthesised and characterised. The best candidates will be selected for oxygen sensing applications.
