Radically enhanced molecular switches.
The mechanism governing the redox-stimulated switching behavior of a tristable [2]rotaxane consisting of a cyclobis(paraquat-p-phenylene) (CBPQT(4+)) ring encircling a dumbbell, containing tetrathiafulvalene (TTF) and 1,5-dioxynaphthalene (DNP) recognition units which are separated from each other along a polyether chain carrying 2,6-diisopropylphenyl stoppers by a 4,4'-bipyridinium (BIPY(2+)) ...
متن کاملIsoindolinone-based molecular switches.
Switches are frequently used to provide external control over the conformation and function of organic and bio-organic molecules. While the use of bistable switches is widespread, multi-stable examples are observed relatively rarely. Reported here is a new class of molecular switch that is capable of forming three stable states of varied geometries, two of which can be induced to interconvert r...
متن کاملMolecular switches at surfaces.
In nature, molecules exploit the interaction with their environment to realize complex functionalities on the nanometer length scale. Physical, chemical and/or biological specificity is frequently achieved by switching of molecules between microscopically different states. Paradigmatic examples are the energy production in proton pumps of bacteria or the signal conversion in human vision which ...
متن کاملMolecular switches and cages
Chemists have developed a large number of synthetic switches, complementing the many types found in nature. Given their prominence in biology, it is not surprisingly that photoswitches, which are actuated by ultraviolet, visible or infrared light, have been an especially productive field of study. Despite their long history, new types of synthetic photoswitches continue to emerge and “old frien...
متن کاملMolecular Rotors as Switches
The use of a functional molecular unit acting as a state variable provides an attractive alternative for the next generations of nanoscale electronics. It may help overcome the limits of conventional MOSFETd due to their potential scalability, low-cost, low variability, and highly integratable characteristics as well as the capability to exploit bottom-up self-assembly processes. This bottom-up...
