| 中文摘要 | a ladder polysilsesquioxanes with side chain of dibenzothiophene groups (bs-lpsq) was successfully synthesized. the ladder structure of bs-lpsq was characterized by maldi-tof ms, xrd, and 1h nmr spectroscopy. differential scanning calorimetry (dsc), thermogravimetric analysis (tga), atomic force microscopy (afm), and spectroscopic analyses revealed that the bs-lpsq has good film-forming ability, high thermal and morphological stability, and good miscibility to the dopant iridium bis(4,6-difluorophenyl)pyridinato-n,c2-picolinate (firpic), high triplet energy, and a wide bandgap. in addition, compared with the ringed polysiloxane bs-psq phosphorescent host material reported previously, the ladder structure of bs-lpsq has not only a higher thermal resistance, but also could prevent molecular aggregation and effectively avoid quenching of fluorescence. thus, the bs-lpsq may be used as a better host for the blue-light-emitting iridium complex firpic. the performance of the electrophosphorescent device, based on the ladder bs-lpsq as the active layer, is superior to that of ringed bs-psq and any other polyhedral oligomeric silsesquioxane (poss)-based or polymer host materials. |
