Modulating Noncovalent Cross-links with Molecular Switches.
Journal of the American Chemical Society, 2019Spiropyran molecular switches, in conjunction with transition metal ions, are shown to operate as reversible polymer cross-linkers. Solutions containing a spiropyran-functionalized polymer and transition metal ions underwent reversible thermally ...

Molecular Switches Based on Molecular Inclusion
1998The synthesis of calix[4]arene-based carceplexes via two different methods is described, as well as a method for modifying the behavior of guests after incarceration. A new approach for the development of a molecular switch is presented.

Phenazine-1,6-dicarboxamides: redox-responsive molecular switches.
Journal of the American Chemical Society, 2019We introduce phenazine-1,6-dicarboxamides as redox-responsive molecular switches. Reduction of their phenazine core transforms it from a hydrogen bond acceptor into a hydrogen bond donor and thus forces the secondary amide substituents to turn around ...

Molecular Switches in Troponin
1998The contraction of vertebrate striated muscle contraction, and hence its work output, is controlled by Ca2+, which binds to troponin (Tn) associated with tropomyosin (TM) and actin in the thin filaments. Tn consists of three subunits: TnC, the Ca(2+)-receptor; TnI, an inhibitor of actomyosin activity; and TnT, anchoring Tn to TM.

Molecular Metal Wires and Molecular Switches
19th International Conference on Advanced Information Networking and Applications (AINA'05) Volume 1 (AINA papers), 2005Owing to their fascinating bonding nature, the metal-metal (M-M) multiple bonds in dinuclear metal complexes have been an interesting and vital research topic. During the past decade, our seminal and systematic approaches on the all-syn oligo-(/spl alpha/-pyridyl)amido ligands coordinated metal ions have successfully opened up a new chapter, extending ...

Spatial periodicity in molecular switching
Nature Nanotechnology, 2008The ultimate miniaturization of future devices will require the use of functional molecules at the nanoscale and their integration into larger architectures. Switches represent a prototype of such functional molecules because they exhibit characteristic states of different physical/chemical properties, which can be addressed reversibly.

The development of molecular fluorescent switches
Trends in Biotechnology, 2001Molecular systems in which fluorescence switches between 'on' and 'off' states when driven by chemical stimuli can be designed according to a few principles. The photochemical mechanisms examined are photoinduced electron transfer, internal charge transfer and excimer formation, with emphasis on the first category.

Molecular Switch on a Metal Surface
The Journal of Physical Chemistry B, 2006We report a theoretical study for the conformational switching of molecules on Au(111) surface in the presence of an applied electric field. Ab initio calculations for N-(2-mercaptoethyl)benzamide indicate that this molecule, when adsorbed, can exist as two stable conformers of nearly equal energies, but the dipoles point in reverse directions with ...

Optical control of molecular switches
Journal of Modern Optics, 2009We review recent applications of quantum control on molecular switches by optical means. We discuss diverse examples, as detection and automatic switching between nucleotide base-pairs and their undesired mutants, controlled operation of multi-configurational molecular devices for quantum information storage, and switching between the two enantiomeric ...
