Hole Transport in Solid Solutions of a Diamine in Polycarbonate

Article abstract of DOI:10.1021/j150664a053

Hole transport has been investigated in films of solutions of N,N'-diphenyl-N,N'-bis(3-methylphenyl)-<1,1'-biphenyl>-4,4'-diamine in bisphenol A polycarbonate.Charge carrier mobilities in excess of 1E-3 cm²/(Vs) have been observed at room temperature at electric fields lower than 1E4 V/cm.The values of hole mobility were between 1E-10 and 1E-3 cm²/(Vs) as the molecular concentration was varied from 9 to 100 wtpercent.At high concentrations of the transport molecule and at fields less than 1E5 V/cm, the mobility is essentially independent of electric field.Field dependence was observed at lower concentrations and high fields.
