Journal ArticleDOI
Visualization of Polymer Deformation Using Microcapsules Filled with Charge-Transfer Complex Precursors.
TL;DR: The visualization of polymer deformation using microcapsules filled with charge-transfer complex precursors is reported and a deformation threshold seems to be present.
Journal ArticleDOI
A mechano- and thermoresponsive luminescent cyclophane
Yoshimitsu Sagara,Yoshimitsu Sagara,Yoan C. Simon,Yoan C. Simon,Nobuyuki Tamaoki,Christoph Weder +5 more
TL;DR: The first fluorescent cyclophane with mechano- and thermoresponsive solid-state fluorescence characteristics is reported and the stimuli-responsiveness is based on molecular assembly changes.
Journal ArticleDOI
Asymmetric Cyclophanes Permit Access to Supercooled Nematic Liquid Crystals with Stimulus-Responsive Luminescence
TL;DR: In this article, an asymmetric cyclophane containing one 1,6-bis (phenylethynyl) pyrene group was synthesized to display a broad nematic phase above ∼110 °C upon being heated.
Journal ArticleDOI
Thermoresponsive low-power light upconverting polymer nanoparticles
David C. Thévenaz,Angelo Monguzzi,Dimitri Vanhecke,Roberto Vadrucci,Francesco Meinardi,Yoan C. Simon,Yoan C. Simon,Christoph Weder +7 more
TL;DR: In this article, highly efficient sensitized triplet-triplet annihilation based upconversion in aqueous suspensions of nanoparticles prepared from 9,10-diphenylanthracene-terminated poly(e-caprolactone) and with platinum octaethylporphyrin as the sensitizer is reported.
Journal ArticleDOI
Morphology of Polymer/Liquid-Crystal Nanotubes: Influence of Confinement†
Martin Steinhart,Sven Murano,Andreas K. Schaper,Tetsuya Ogawa,Masaki Tsuji,Ulrich Gösele,Christoph Weder,Joachim H. Wendorff +7 more
TL;DR: In this paper, the pore diameter of a polymer/liquid-crystal (LC) tube is reduced to 60 nm, which results in a confinement-induced transition from a wetting state to a nonwetting state and solid rods with a sequential morphology.
