Professor Koji Araki of the University of Tokyo kindly suggested that we offer 1,3,6,8-tetrabromopyrene (Aldrich Prod. No. 717274) as a building block for the synthesis of larger, luminescent materials. Molecules that are light emitters in the visible region are potentially useful in the fabrication of organic light emitting diodes (OLEDs).1,2 For example, this starting material is used to create a variety of pyrene-core molecules, using high-yielding reactions such as Suzuki coupling, that can efficiently emit blue-light with efficiencies of 0.9.3
