“…Those techniques usually involve UV or thermal crosslinking reaction and these approaches were proved as useful tools for application on charge injecting, transporting, blocking and emitting layers of OLEDs [9][10][11]. Both polymers and monomer precursors were used for obtaining the crosslinked polymer films [12][13][14]. Carbazole derivatives are widely used for the preparation of cross-linked electroactive layers, due to simplicity of introduction of reactive functional groups into carbazole moiety and due to valuable properties of carbazole derivatives, such as high hole-mobilities and high photoluminescence quantum yields [11,12,14,15].…”

“…Carbazole derivatives were extensively investigated for applications in different electronic devices [19,20]. The high level of interest in carbazole derivatives emerged due their hole transporting properties, strong absorption and efficient luminescence, good stability versus oxidation and easiness of carbazole derivatization [12,[21][22][23][24].…”

A new epoxy resin containing carbazole moieties was synthesized and added in several proportions to diglycidylether of bisphenol A (DGEBA) and trimethylolpropane tris(3-mercaptopropionate) (TTMP) formulations that were thermally cured by thiol-epoxy click reaction. The curing was catalyzed by a latent amine precursor, which after triggering at high temperature liberates the amine that enables the formation of thiolate groups. The curing process of the different formulations was monitored by calorimetric analysis, which allowed to observe that the increase of the proportion of the synthesized epoxy resin with carbazole groups in the formulation decreased the curing rate. However, all these formulations cured quickly after triggering, which make them adequate for the formation of layers in multilayer devices.\ud \ud Thermal characteristics of the obtained thermosets were determined by calorimetric, thermomechanical and thermogravimetric analysis. The obtained thermosets have good thermal stability. Their glass transition temperature increased when the proportion of the carbazole containing resin was increased in the formulation. The photophysical properties of the thermoset films were studied and it was proved that they exhibit fluorescence in the range of 352 to 369 °C.Postprint (author's final draft
