| 中文摘要 | a series of 9,9'-spirobifluorene/oxadiazole hybrids with various linkages between two components, namely sbf-p-oxd (1), sbf-m-oxd (2), and sbf-o-oxd (3) are designed and synthesized through suzuki cross-coupling reactions. the incorporation of a rigid and bulky spirobifluorene moiety greatly improves their thermal and morphological stability, with t-d (decomposition temperature) and t-g (glass transition temperature) in the ranoes of 401-480 degrees c and 136-210 degrees c, respectively. 2 and 3 with meta- and ortho-linkage display higher triplet energy and blue-shifted absorption and emission than their para-linked analogue 1 owing to the decreasing pi-conjugation between the two components. their homo and lumo energy levels depend on the linkage modes within the range of 5.57-5.64 ev and 2.33-2.49ev, respectively. multilayer deep red electrophosphorescent devices with 1-3 as hosts were fabricated and their el efficiencies follow the order of 3 (o) > 2 (m) > 1 (p), which correlates with their triplet energy and the separation of homo and lumo distributions at molecular orbitals. the maximum external quantum efficiencies of 11.7% for green and 9.8% for deep red phosphorescent organic light-emitting diodes (oleds) are achieved by using 2 and 3 as host materials. respcctively. |
