| 中文摘要 | herein, an insulating fluorinated polyimide (f-pi) is utilized as an ultrathin buffer layer of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (pedot:pss) in polymer light-emitting diodes to enhance the device performance. the selective solubility of f-pi in common solvents avoids typical intermixing interfacial problems during the sequential multilayer spin-coating process. compared to the control device, the f-pi modification causes the luminous and power efficiencies of the devices to be increased by a factor of 1.1 and 4.7, respectively, along with almost 3-fold device lifetime enhancement. photovoltaic measurement, single-hole devices, and x-ray photoelectron spectroscopy, are utilized to investigate the underlying, mechanisms, and it is found that the hole injection barrier is lowered owing to the interactions between the pedot:pss and f-pi. the f-pi modified pedot:pss layer demonstrates step-up ionization potential profiles from the intrinsic bulk pedot:pss side toward the f-pi-modified pedot:pss surface, which facilitate the hole injection. |
