Taming macromolecules with light : lessons learned from vibrational spectroscopy
(Wiley, 2017-09-12)
Exciting new applications, from large-area nanopatterning and templating to soft light-powered robotics, are emerging from the fundamental research on light-triggered changes in macromolecular systems upon photoisomeriza-tion ...
Influence of supramolecular interaction type on photoresponsive azopolymer complexes : a surface relief grating formation study
(American Chemical Society, 2016-06-24)
The influence of the supramolecular interaction type—hydrogen bonding, proton transfer, and pure ionic bonding—on photoresponsive behavior, particularly surface relief grating (SRG) inscription, has been investigated using ...
Bridging the gap between the mesoscopic 2D order–order transition and molecular-level reorganization in dot-patterned block copolymer monolayers
(American Chemical Society, 2016-11-21)
Langmuir–Blodgett (LB) films of amphiphilic block copolymers (BCs) form well-defined nanostructures with long-range order useful, for instance, for nanolithography applications. Nanostructures with a 2D circular micelle ...
Effect of hydrogen-bond strength on photoresponsive properties of polymer-azobenzene complexes
(NRC Research Press & Canadian Society for Chemistry, 2020-04-16)
Supramolecular complexation between photoresponsive azobenzene chromophores and a photopassive polymer host offers synthetic and design advantages compared with conventional covalent azo-containing polymers. In this context, ...
Photocontrol of supramolecular azo-containing block copolymer thin films during dip-coating : toward nanoscale patterned coatings
(American Chemical Society, 2019-05-07)
Dip-coating allows nanostructured block copolymer (BCP) thin film fabrication in a fast and facile one-step process. It can also be coupled with external controls, such as illumination. Herein, we expose several design ...
In situ photocontrol of block copolymer morphology during dip-coating of thin films
(American Chemical Society, 2015-09-28)
We demonstrate a unique combination of simultaneous top-down and bottom-up control of the morphology of block copolymer films by application of in situ optical irradiation during dip-coating. A light-addressable and ...
Molecular-level study of photoorientation in hydrogen-bonded azopolymer complexes
(American Chemical Society, 2018-01-25)
To optimize azobenzene-containing materials for applications such as
rewritable waveguides and holographic data storage, it is imperative to understand the effect
of the azobenzene structure on the photoresponse of the ...
