“…[6,82] However, data on electron transport for disordered systems is rare. [7,83] The apparent reason for the low mobility of electrons in disordered organic solids is trapping. A high effort is needed to clean organic solids, since oxidation often produces electron traps but no hole traps.…”

Herein, we focus on the principles of photoconduction in random semiconductors—the key processes being optical generation of charge carriers and their subsequent transport. This is not an overview of the current work in this area, but rather a highlight of elementary processes, their involvement in modern devices and a summary of recent developments and achievements. Experimental results and models are discussed briefly to visualize the mechanism of optical charge generation in pure and doped organic solids. We show current limits of models based on the Onsager theory of charge generation. After the introduction of experimental techniques to characterize charge transport, the hopping concept for transport in organic semiconductors is outlined. The peculiarities of the transport of excitons and charges in disorderd organic semiconductors are highlighted. Finally, a short discussion of ultrafast transport and single chain transport completes the review.

“…Electron mobility is evaluated in a voltage range 3-7 V ($3-7 Â 10 5 V cm À1 electric eld), found to be 4. 32 However, the later reports are on very thick polymers ($4 mm) and are not directly applicable in the case of OLEDs. Our reports are directly applicable here because of relatively low thickness ($100 nm) of OLEDs.…”

Herein, we report polybenzodioxane polymer (PIM-1), a multifunctional n-type emitter with strong green luminescence, and its suitability as an electron transport layer for OLEDs devices. The BrunauerEmmett-Teller (BET) test and photo-electrical properties of as-synthesized PIM-1 confirm the presence of large microporosity and excellent electron mobility. The photoluminescence (PL) spectroscopy shows the intense green emission at 515 nm upon 332 nm excitation wavelength. Moreover, the Hall effect study reveals the negative Hall resistivity, which indicates that PIM-1 possesses n-type semiconductor . Additionally, the electron mobility is found to be 4.4 Â 10 À6 cm 2 V À1 s À1 . Hence, these results demonstrate that PIM-1 could be an ultimate choice as an n-type emitter for the next generation of advanced electronic devices.
