New electron transport materials having the following general structure shown in Figure 1 have been developed. We synthesized them and examined their properties. These compounds showed good compatibility to a polycarbonate and good solubility in common organic solvents. Electron transport properties of these compounds were investigated. Electron drift mobilities have been measured as a function of the concentration and electric field by the conventional time-of-flight technique. They showed nondispersive electron transport in composition films. The values of electron mobility ranged from 10−8 to 10−4 cm2/Vs as the molecular concentration was varied from 20 to 60 wt%.
