Binary Ion Organic Systems for Next Generation Solid State Light Sources (BRIGHTS)

The planned industrial research project ‘Binary ion organic systems for next generation solid state light sources’ (BRIGHTS) aims to develop efficient light-emitting electrochemical cells (LECs) using a previously unexplored ion organic phosphor/dopant binary emitting system in the light emitting layer.The project has two interrelated objectives:1)Develop organic base-material/do-article binary emitting systems for LEC devices using small ionic fluorescent molecules (MJLMs). The development of MJLM will draw on the expertise of the project applicant related to the TSCT mechanism between the aromatic donor and the cationic acceptor. This type of TSCT promotes intensive solid emission and prevents aggregation induced damping (AIS);2)Establishment of LEC devices using the developed MJLM binary systems. LEC devices will be designed and manufactured using optimised MJLM binary systems. The electrical and electroluminescent properties of LEC devices will be studied, as well as the parameters for the formation of the active emitter layer will be optimized.Key actions:The design and synthesis of new MJLM for the formation of ionic organic phosphor/dopant binary emitter systems;Exploration of photophysical, photoelectric and thermal properties of the developed MJLM systems, such as photoluminescent quantum output, singlet and triplet energy, holes and electron transport energy levels, as well as charge transfer properties;Design, optimization and production of a prototype LEC device using an ionic organic phosphor/dopant binary emitter system in the light emitter layer of LEC devices.The expected results of the project are: 1) an ionic organic phosphor/dopant binary emitter system based on low molecular weight MJLM emitters; 2) patentable LEC prototype; 3) three open-access publications in top-level scientific journals and participation in six scientific conferences; 4) One international PCT patent application. The results of the project will contribute to the growth of the Latvian economy by developing innovative products, improving innovation capacity, as well as promoting and supporting technological progress.The planned interdisciplinary research project BRIGHTS conforms to the following OECD classification of science and technology fields: 1.4. ‘Chemistry’, 1.3. Physics and astronomy and 2.5. Materials Science. The project is not related to economic activity and contributes to the Latvian Smart Specialisation Strategy area ‘Smart materials, technologies and engineering systems’ and corresponds to NACE code 72.19 - other research and experimental development in natural sciences and engineering. Project BRIGHTS will be implemented by young scientists, doctoral students and master students.Project implementation:Consortium leader Latvian Institute of Organic Synthesis (LOSI), Riga, Latvia, Leading researcher - Prof. Dr. Edgars Sūna.Project will be implemented in cooperation with two partners: Partner 1: Institute of Solid State Physics of the University of Latvia (CFI), Riga, Latvia. Leading researcher - Dr. Aivars Vembris.Partner 2: SIA OLEC, SIA, Riga, Latvia. The main researcher - Dr. chem. Artis Kinēns.Eligible costs of the project: EUR 655 526.95 (ERDF funding EUR 509 344.44).Project duration: 36 monthsStart of project: 1 July 2025 Keywords: heterocycles, organic cations, charge transfer through space, aggregation emission (AIE), light-emitting electrochemical cells (LEC)
