Internal Dynamics of a Supramolecular Nanofiber
A large variety of functional self-assembled supramolecular nanostructures have been reported over recent decades. The experimental approach to these systems initially focused on the design of molecules with specific interactions that lead to discrete geometric structures, and more recently on the kinetics and mechanistic pathways of self-assembly. However, there remains a major gap in our unde...
متن کاملPhotochromism in sound-induced alignment of a diarylethene supramolecular nanofibre.
A photochromic supramolecular nanofibre, composed of a diarylethene derivative, exhibits hydrodynamic alignment upon exposure to the audible sound. The aligned nanofibre outputs linear dichroism (LD), whose wavelength region can be switched reversibly with UV and visible light.
متن کاملEffect of supramolecular structure on polymer nanofibre elasticity.
Polymer materials of reduced size and dimensionality, such as thin films, polymer nanofibres and nanotubes, exhibit exceptional mechanical properties compared with those of their macroscopic counterparts. We discuss here the abrupt increase in Young's modulus in polymer nanofibres. Using scaling estimation we show that this effect occurs when, in the amorphous (non-crystalline) part of the nano...
متن کاملSpectroscopic visualization of sound-induced liquid vibrations using a supramolecular nanofibre.
The question of whether sound vibration of a medium can bring about any kind of molecular or macromolecular events is a long-standing scientific controversy. Although it is known that ultrasonic vibrations with frequencies of more than 1 MHz are able to align certain macromolecules in solution, no effect has yet been reported with audible sound, the frequency of which is much lower (20-20,000 H...
متن کاملSupramolecular assembly dynamics.
R progress in the synthetic chemistry of supramolecular assemblies has created many new structural types. With the proliferation of new structures has come increasing interest in the properties and behavior of these assemblies. Does the cooperativity of constituent components lend an assembly new properties distinct from the components themselves? Do the properties of an assembly make it suitab...
