Scintillators are materials which exhibit scintillation – the property of luminescence when excited by ionizing radiation. Luminescent materials, when struck by an incoming particle, absorb its energy and scintillate. POPOP, 1,4-bis-(5-phenyl-oxazolyl-2)-benzene, is one of the organic scintillators that have applications in detecting the nuclear rays and charged particles. Hence, synthesise of POPOP have been focused and some synthetic methods have been investigated. A new and efficient method for the preparation of POPOP is presented in this paper. An intermediate was synthesized bye the reaction of 2-aminoacetophenone with terephethaloyl dichloride. The oxazole rings in the final product (POPOP) were then formed by the reaction of this intermediate with concentrated sulfuric acid yielding the final product.
