2-chloro-4-(biphenyl-4-yl)-6-phenyl-1,3,5-triazine

2-([1,1'-Biphenyl]-4-yl)-4-chloro-6-phenyl-1,3,5-triazine, also called BPPTRZ-2Cl, PBPTZ and 2-(4-Biphenylyl)-4-chloro-6-phenyl-1,3,5-triazine, is a white powder that needs to be stored in the inert gas (nitrogen or argon) at 2-8 ° C. As a photoelectric material, it is often used as a bipolar material for synthesizing organic light emitting diodes. It can also be used as a material for thermally activated delayed fluorescence emitter[1].
