We apply the Time of Flight (TOF) technique to study carrier mobility in N, N'-diphenyl-N,N'-bis(3-methylphenyl) -1,1-biphenyl-4,4'-diamine (TPD) and tris(8-hydroxyquinolato) aluminium (Alq3). These materials are two examples of, respectively, hole and electron transporting molecular materials. Measurements are performed in free air or under vacuum varying the experimental parameters such as laser pulse intensity and single shot irradiation. We observe a transition from dispersive to non dispersive transport changing the experimental conditions.
