In this study, new silane-containing polymers, called OSTE-AS polymers, were developed based on off-stoichiometry thiol–ene polymers. These polymers can bond to silicon wafers without pretreatment of the surface by an adhesive. Silane groups were included in the polymer using allylsilanes, with the thiol monomer as the target of modification. The polymer composition was optimized to provide the maximum hardness, the maximum tensile strength, and good bonding with the silicon wafers. The Young’s modulus, wettability, dielectric constant, optical transparency, TGA and DSC curves, and the chemical resistance of the optimized OSTE-AS polymer were studied. Thin OSTE-AS polymer layers were obtained on silicon wafers via centrifugation. The possibility of creating microfluidic systems based on OSTE-AS polymers and silicon wafers was demonstrated.

Therefore, terbium-based emitters, containing anionic ligands, able to both increase the hole mobility and to sensitize terbium luminescence, were purposefully obtained within the composite films, containing the recently studied host material PO4, able to increase electron-transport properties and also to ensure terbium luminescence. As a result, the luminance of 332 cd/m2 was reached, which is one of the highest results for solution-processed OLEDs based on terbium complexes.
