High performance organic thin film transistor based on pentacene derivative: 6,13-dichloropentacene

Theoretical comparative studies on transport properties of pentacene, pentathienoacene, and 6,13‐dichloropentacene

“…The crystal structures can be found in Refs. [25,27,56]. Even though the structures of pentacene, PTA and DCP are similar, they exhibit very different intrinsic transport properties.…”

“…Due to the introduction of the chlorine substituents, DCP molecules adopt a slipped face to face packing mode in the crystals with a large intermolecular p-p overlap, suggesting the potential applications of high mobility organic semiconductors. In addition, DCP has a good environmental stability and decent solubility, [27] which make it a promising material applied in organic electronics. [27] Although the charge transport mechanisms have been studied for several decades, [29][30][31][32][33][34][35] the theoretical understanding is still limited, due to the complexities of organic materials and wide variety of structures.…”

[34] Regardless of the charge transport mechanisms, the intermolecular coupling and reorganization energy were found to strongly influence charge transport properties.…”

“…It displayed a high mobility (up to 9.0 cm 2 V 21 s 21 ), which is among the highest values reported for pentacene derivatives so far. [27,28] DCP as a derivative of pentacene, can be easily synthesized and purified. Due to the introduction of the chlorine substituents, DCP molecules adopt a slipped face to face packing mode in the crystals with a large intermolecular p-p overlap, suggesting the potential applications of high mobility organic semiconductors.…”

High‐Performance Organic Field‐Effect Transistors Based on Single and Large‐Area Aligned Crystalline Microribbons of 6,13‐Dichloropentacene

“…[ 9 ] 6,13-dichloropentacene (DCP, chemical structure see Figure 1 a), as a derivative of pentacene, could be easily synthesized and purifi ed, and displayed good stability. [ 10 ] Single crystals revealed, due to the introduction of chlorine substituents, DCP adopted slipped π − π stacking model with large intermolecular overlap, and C-H-Cl interactions between neighboring DCP molecules were observed, suggesting the potential applications of DCP as high performance organic semiconductor. Herein, crystalline ribbons of DCP were prepared.…”
