Nanosized red light-emitting materials in which fluorene, thiophene and benzothiadiazole moieties are introduced into nanosized cores – polyhedral oligomeric silsesquioxane (POSS) - were synthesized by Suzuki coupling and hydrosilation reaction. The molecular structures of the nanosized materials were confirmed by 1H-NMR and MALDI-TOF. Thermal properties were characterized by DSC and TGA. Optical properties were investigated by UV-vis and PL and the PL spectra showed red region emissions. The materials were soluble in common organic solvents and can be spin-coated on ITO or quartz plates. Homogeneous films were formed. The results showed that the nanosized materials are promising red light-emitting materials for solution processing technique. |
