Functionalized Pentacene Active Layer Organic Thin-Film Transistors

Organic thin‐film transistors with active layers of five different functionalized pentacene derivatives (see Figure) have been fabricated. The pentacene molecules are functionalized to encourage face‐to‐face molecular interactions and thus increase π‐orbital overlap and carrier field‐effect mobility...

Zusammenfassung:Organic thin‐film transistors with active layers of five different functionalized pentacene derivatives (see Figure) have been fabricated. The pentacene molecules are functionalized to encourage face‐to‐face molecular interactions and thus increase π‐orbital overlap and carrier field‐effect mobility. Devices fabricated using triisopropylsilyl pentacene have the highest field‐effect mobility (0.4 cm2 V–1 s–1) and on/off current ratio (106).
