Crystalline Microwires of Rubrene for Chemical Sensing

Crystalline Microwires of Rubrene for Chemical Sensing Abstract Crystalline nano- and microwires of Rubrene are synthesized from a gas phase deposition method and the sensing behavior of microwires is studied. The resistivity of the microwires in N2 is 8.82 ± 1.80 × 103 Ω·cm. The current of the microwires increases when the microwires are exposed to O2 and decreases on exposure to electron deficient aromatic molecules, such as nitrobenzene and benzaldehyde, suggesting the resistivity change of rubrene microwires may have potential applications in selective chemical sensors for O2 and electron deficient aromatic molecules, particularly nitro-containing explosive chemicals. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Analytical Chemistry Letters Taylor & Francis
