文摘

The electron mobilities in vapor-phase-deposited thin films of three fluorinated phenoxy boron subphthalocyanine (F₅BsubPc, F₁₂BsubPc, and F₁₇BsubPc) molecules are measured using admittance spectroscopy. The mobilities are found to be field dependent, following a Poole鈥揊renkel type relation, and are in the range of 10^鈥? cm² V^鈥? s^鈥? at typical operating field strengths for devices such as organic photovoltaic cells. A new F₅BsubPc crystal polymorph (尾-) is disclosed and its determination is critical to our ability to correlate charge carrier mobility and solid-state packing for each compound.
