Organic Nanofibers Embedding Stimuli-Responsive Threaded Molecular Components

While most of the studies on molecular machines have been performed in solution, interfacing these supramolecular systems with solid-state nanostructures and materials is very important in view of their utilization in sensing components working by chemical and photonic actuation. Host polymeric materials, and particularly polymer nanofibers, enable the manipulation of the functional molecules c...

c radiation induced self-assembly of fluorescent molecules into nanofibers: a stimuli-responsive sensing†

Low dose detection of g radiation remains critical for radiology therapy and nuclear security. We report herein on a novel dual-band fluorescence sensor system based on a molecule, 4-(1H-phenanthro[9,10-d]imidazol-2-yl)-N,N-diphenylaniline (PI-DPA), which can be dissolved into halogenated solvents to enable expedient detection of g radiation. The limit of detection was projected down to 0.006 G...

Heteroepitaxial Organic Nanofibers

Stimuli-Responsive Polymer Nanotube Arrays

Nanotube arrays, composed of materials such as carbon, titania, and zinc oxide, have shown potential as conductors, energy conversion devices, actuators, and adhesives. Such nanoscale constructs are particularly novel for their high area-to-volume and length-to-diameter aspect ratios that lead to physical and chemical properties more interesting than their bulk counterparts. However, the stimul...

Stimuli-responsive smart gating membranes.

Membranes are playing paramount roles in the sustainable development of myriad fields such as energy, environmental and resource management, and human health. However, the unalterable pore size and surface properties of traditional porous membranes restrict their efficient applications. The performances of traditional membranes will be weakened upon unavoidable membrane fouling, and they cannot...
