摘要：

The electron mobilities in vapor-phase-deposited thin films of three fluorinated phenoxy boron subphthalocyanine (F(5)BsubPc, F(12)BsubPc, and F(17)BsubPc) molecules are measured using admittance spectroscopy. The mobilities are found to be field dependent, following a Poole-Frenkel type relation, and are in the range of similar to 10(-4) cm(2) V-1 s(-1) at typical operating field strengths for devices such as organic photovoltaic cells. A new F(5)BsubPc crystal polymorph (beta-) is disclosed and its determination is critical to our ability to correlate charge carrier mobility and solid-state packing for each compound.
