Charged Carrier Mobility Study in Col(h) Mesophase of Perfluoroalkylated Triphenylene Derivatives
The charged carrier mobility was measured for a Col(hd) mesophase of a perfuluoroalkylated triphenylene derivative to compare that of the corresponding non-fluorinated alkoxy derivative. The mobility was determined for both positive and negative charges which is in the order of 10(-4) cm(2) V-1 s(-1). In the negative electrode inllumination, the transient photocurrent decay carves consist of the fast and slow components and the latter is probably derived from an ionic transport. Though the perfluoroalkylated triphenylene shows the higher thermal stability of a Colhd mesophase, than the corresponding hydrogen homolougue, the mobility is in the same order and the ambipolar character is shared.
