2,2',7,7'-Tetrabromo-9,9'-spirobifluorene Structural

What is 2,2',7,7'-Tetrabromo-9,9'-spirobifluorene?

Description

2,2′,7,7′-Tetrabromo-9,9′-spirobifluorene is a spirobifluorene (SBF) derivative and is used as a blue-emitting material in electroluminescent devices. The spirobifluorene linkage in the molecule helps in decreasing the crystallization tendency and also increases the colour stability by preventing the formation of aggregates or excimers. They possess high photoluminescence efficiency and good chemical stability.

Chemical properties

White to light yellow powder
