| Hazard Information | Back Directory | [Description]
SPPO1, 9,9-Spirobifluoren-2-yl-diphenyl-phosphine oxide has a spirobifluorene structure with an electron deficient polar diphenyl-phosphine oxide moiety attached. The polarity in the P=O double bond can lead to a high triplet energy state, which is highly desirable in host materials for an efficient host-to guest energy transfer in an OLED. |
