	These are voltammograms for various components that might be of use in building OLEDs.		These are cyclic voltammograms for various components that might be of use in building OLEDs.
	Following TPD, as we sweep towards the positive is the first one electron oxidation and then a second, and then the reduction of the di-cation radical and then the reduction of the cation radical back to the neutral state. In an OLED we only worry about the first of the two one electron transfer processes.

	The mobility for electrons passing into the HTL is much lower than the mobility of holes passing into the ETL. In recent years there has success in balancing these mobilities but even in polymer light emitting diodes it is still a problem.
