    摘要: The present invention generally relates to the fabrication of molecular electronics devices from molecular wires and Single Wall Nanotubes (SWNT). In one embodiment, the cutting of a SWNT is achieved by opening a window of small width by lithography patterning of a protective layer on top of the SWNT, followed by applying an oxygen plasma to the exposed SWNT portion. In another embodiment, the gap of a cut SWNT is reconnected by one or more difunctional molecules having appropriate lengths reacting to the functional groups on the cut SWNT ends to form covalent bonds. In another embodiment, the gap of a cut SWNT gap is filled with a self-assembled monolayer from derivatives of novel contorted hexabenzocoranenes. In yet another embodiment, a device based on molecular wire reconnected a cut SWNT is used as a sensor to detect a biological binding event.

    摘要: Provided is an alicyclic alcohol compound which can be used as a raw material for a compound perfume, and which has excellent floral-green-like aromas which are crisp and fresh; also provided are a manufacturing method for the same, and a perfume composition which contains the alicyclic alcohol compound. An alicyclic alcohol compound having a specified structure represented by chemical formula (1) has excellent floral-green-like aromas which are crisp and fresh; and a method for manufacturing the alicyclic alcohol compound represented by chemical formula (1) by reacting, in the presence of hydrogen fluoride, 4-isopropyl-1-methylcyclohexene and carbon monoxide, isomerizing the resulting 4-isopropyl-1-methylcyclohexane carboxylic acid fluoride, thus making 2-methyl-2-(4-methylcyclohexyl)-propionyl fluoride, reacting with alcohol and acquiring a cyclohexane carbonyl compound, and then reducing the cyclohexane carbonyl compound.
