Descrizione

Applicazioni

2-(4-tert-Butylphenyl)-5-(4-biphenylyl)-1,3,4-oxadiazole (PBD) can be used as a hole-blocking material in the fabrication of multilayer polymer light-emitting diodes to enhance the efficiency of the device. It is also used as an additive to fabricate the polyurethane (PU) based bistable nonvolatile memory devices with resistive switching characteristics. By incorporating PBD with PU, device performance showed significant improvement, with increase in ON/OFF ratio by two orders of magnitude and a long retention period of over five hours. PBD is also an organic fluorescent molecule used to prepare plastic scintillators.
