1.1.1. Brief description of the project summary The aim of the project is to create new and effective amorphous phase-forming and light-emitting organic materials – molecular glasses, the further technological development of which in practical applications should be implemented with low cost solution treatment methods. Structurally different compounds will be created, with wavelengths of light emitted located in different areas of visible light. The production of monochrome and white light emitting diodes (OLED and wOLED) is planned to demonstrate the practical application of the project approach using the most promising materials. The project will be implemented by synthesis, purification, proof of structure, determination of thermoplastic properties and initial assessment of the light emission properties and efficiency of materials. Further, physical processes related to material light emissions and electroluminesence will be studied, i.e. the kinetics of emission processes, the determination of the energy levels of compounds and projectile mobility, as well as the design of OLED. The structural approach of the materials to be developed will be based on light emitting active molecules that will be chemically modified with solubility and amorphous phase formation support groups (triphenylmethane derivatives). From the target joints it will be possible to make thin vitreous layers with rotary coating and other solutions treatment methods from slightly volatile solvents. Blue fluorescent purine derivatives will be used as emitting components, as well as in the visible spectrum in the green to red region phosphorescent iridium (III) cyclometalised complexes.1.1.2.Complete description of the project summary The research carried out in the project is considered a fundamental research and is interdisciplinary, covering chemical and physics industries (OECD FOS classification 1.4 and 1.3). The project will be implemented as a result of cooperation between Riga Technical University (RTU) and Institute of Solid Material Physics of the University of Latvia (LUCFI). A new scientific group will be established, attracting human resources in the amount of 5,2 FTE during the project implementation period, consisting of one scientist, 3 young scientists and 6 doctoral/master’s students. The project will be implemented by RTU partner through activities related to chemical research, namely, development of materials design, synthesis of compounds, purification, proof of structure, determination of thermoplastic properties and initial assessment of light emission properties and efficiency of materials. LUCFI partner will perform physical processes related to material light emissions and electroluminesence, i.e. kinetics of emission processes, determination of energy levels of compounds and projectile mobility, as well as design of OLED and wOLED. The structural approach of the materials to be developed will be based on light emitting active molecules that will be chemically modified with solubility and amorphous phase formation support groups.

Blue fluorescent purine derivatives will be used as emitting components, as well as in the visible spectrum in the green to red region phosphorescent iridium (III) cyclometalised complexes. The results of these studies will be reflected in 8 original publications in magazines indexed to the SCOPUS database and whose citation index amounts to at least 50 per cent of the industry average citation index.The total project costs are estimated at EUR 648330.88, of which ERDF support will amount to EUR 551081.25. Project implementation will last 36 months from 1 April 2017 to 31 March 2020
