Functionalized pentacene: improved electronic properties from control of solid-state order.
Molecular order has proven to be a significant factor in the performance of devices based on organic semiconductors. Recent studies involving solubilized versus unsubstituted thiophene oligomers have demonstrated that modifications which increase orbital overlap in the solid state can improve device performance by more than an order of magnitude.1 Similar studies on pentacene, a compound which ...
متن کاملPhotoresponse of the conductivity in functionalized pentacene compounds
We report the investigation of the photoresponse of the conductivity of a recently synthesized class of organic semiconductors based on functionalized pentacene. These materials form high quality single crystals that exhibit a thermally activated resistivity. Unlike pure pentacene, the functionalized derivatives are readily soluble in acetone, and can be evaporated or spincast as thin films for...
متن کاملOligomers and Polymers Based on Pentacene Building Blocks
Functionalized pentacene derivatives continue to provide unique materials for organic semiconductor applications. Although oligomers and polymers based on pentacene building blocks remain quite rare, recent synthetic achievements have provided a number of examples with varied structural motifs. This review highlights recent work in this area and, when possible, contrasts the properties of defin...
متن کاملPentacene-based organic transistors
This report discusses some of the electrical and optical properties of thin films of the organic semiconductor pentacene fabricated using thermal evaporation. Conductivities of between 1.84 × 10 Ω cm and 7.49 × 10 Ω cm are reported. Transistors using thermally evaporated pentacene were fabricated and mobilities of up to 0.03 cmVs were obtained.
متن کاملClustering of pentacene and functionalized pentacene ions in a matrix-assisted laser desorption/ionization orthogonal TOF mass spectrometer.
A high-performance orthogonal time-of flight (TOF) mass spectrometer, in combination with the matrix assisted laser desorption/ionization (MALDI) source operating at elevated pressure ( approximately 1 torr in N(2)), was used to perform MALDI-TOF analyses of pentacene and some of its derivatives with and without an added matrix. These molecules are among the most interesting semiconductor mater...
