rotaxane การใช้

• The switch mechanism consisted of rotaxane molecules sandwiched between two crossed wires.
• More recently, rotaxane with a CB [ 8 ] wheel was synthesized.
• This rotaxane can bind neutral guest molecules.
• They have coaxed ringlike groupings of rotaxane molecules to exhibit the on / off behavior of transistors.
• David Alan Leigh's lab built synthetic ribosome using a chemical structure based on a rotaxane.
• This encumbrance can be attenuated by the formation of a rotaxane around the dye to protect it from nucleophiles.
• The structure of the machine is based on a rotaxane, which is a molecular ring sliding along a molecular axle.
• With a small ligand such pyridine that binds manganese from inside the cavity of the rotaxane, epoxidation happens outside the catalyst.
• And, because rotaxane molecule transistors could be switched on and off using light, there would be no bulky wire interconnections needed.
• At each intersection, a molecular switch _ a rotaxane molecule or one of its successors _ would be wedged between the two wires.
• Calixarenes have been used as the macrocycle portion of a rotaxane and two calixarene molecules covalently joined together by the lower rims form carcerands.
• A "'rotaxane "'is a dissociation ( unthreading ) of the components since this would require significant distortion of the covalent bonds.
• Each bit in the device consists of a silicon and a titanium crossbar with around 100 rotaxane molecules filling in the space between them at perpendicular angles.
• However, examples of rotaxane substructure have been found in naturally occurring peptides, including : cystine knot peptides, cyclotides or lasso-peptides such as microcin J25.
• Reporting their latest experimental results, scientists showed how a synthetic " electronically active " molecule called rotaxane could function as a binary switch when suspended between electrodes.
• The electrons have to jump first onto a rotaxane molecule to get across, a move Heath likened to a hiker stepping onto a stone to get across a river.
• Nolte and coworkers developed an artificial processive enzyme in a form of manganese porphyrin rotaxane that treads along a long polymer of alkene and catalyze multiple rounds of alkene epoxidation.
• Two years ago, scientists at HP and UCLA announced that they had created a custom-designed, carbon-based molecule called rotaxane that could act as a switch.
• Last summer, the UCLA group, working with computer architects and chemists at Hewlett-Packard, reported that it had developed a nonreversible switch based on a molecule known as rotaxane.
• The UCLA and Hewlett-Packard team used synthetic, Y-shaped molecules of a substance called rotaxane, sandwiched in a single-molecule-thick layer between lattices of ordinary metallic wires.
