Highly efficient organic–inorganic electroluminescence materials for solution-processed blue organic light-emitting diodes†
Abstract
A new and novel organic–inorganic light-emitting material (POSS–DPCz) behaves as an effective chromophore and offers substantially improved fluorescence-color purity and quantum yield compared to control DPCz without incorporated POSS. When POSS–DPCz was utilized as an emissive layer in a solution-processed three-layer OLED device, the performance of the resulting device is almost two times higher than that of the control DPCz-based device.
