- Rewritable Optical Storage with a Spiropyran Doped Liquid Crystal Polymer Film
Gia Petriashvili, Maria Penelope De Santo, Lali Devadze, Tsisana Zurabishvili, Nino Sepashvili, Ramla Gary and Riccardo Barberi

Rewritable optical storagehas been obtained in a spiropyran doped liquid crystal polymer film. Pictures can be recorded on films upon irradiation with UV light and they can be rapidly erased using visible light. Films present good resistance to photofatigue and high spatial resolution and they are suitable for real-time image recording applications.

A redox-switchable polyaniline wrinkling system, with a high switching speed and excellent reversibility, is demonstrated here for the first time. The wrinkled/dewrinkled states on polyaniline film are reversibly modulated through a simple chemical redox process along with the conversion between different redox states. This work paves the way to fabricate redox-responsive surface patterns.
- Imparting Nonfouling Properties to Chemically Distinct Surfaces with a Single Adsorbing Polymer: A Multimodal Binding Approach
Ângela Serrano, Stefan Zürcher, Samuele Tosatti and Nicholas D. Spencer
Article first published online: 9 FEB 2016 | DOI: 10.1002/marc.201500683
Nonfouling, surface-active polymers carrying binding groups capable of adsorbing onto different substrates are described. The developed versatile postmodification protocol allows the creation of a polymer that maintains its surface functionality under a variety of harsh conditions. Ethylene glycol surface-density calculations show that this strategy generates a significantly denser packing than current approaches and readily allows the fabrication of a broad combinatorial matrix.
- Color-Transformable Silicone Elastomers Prepared by Thiol-Ene Reaction with Potential Application in UV-LEDs
Yujing Zuo, Zhiming Gou, Jie Zhang and Shengyu Feng
Article first published online: 4 FEB 2016 | DOI: 10.1002/marc.201500671
The first example of a dual-component elastomer that can emit yellow and red primary colors at different irradiation conditions. Colorful UV-LEDs were further fabricated from the solution medium through an “in situ” cross-linking method, and the device also showed color changing property when the light was turned on.
- Orthogonal Synthesis of Block Copolymer via Photoinduced CuAAC and Ketene Chemistries
Mehmet Atilla Tasdelen, Omer Suat Taskin and Cumali Celik
Article first published online: 4 FEB 2016 | DOI: 10.1002/marc.201500563
A simple approach combining photoinduced copper (I)-catalyzed alkyne-azide cycloaddition (CuAAC) and ketene chemistry reactions is proposed to synthesize poly(ethylene glycol)-b-polystyrene copolymer starting from easily accessible blocks, poly(ethylene glycol) methyl ether, and azido terminated polystyrene. The process proceeds either simultaneously or sequentially in a one-pot procedure under near-visible light irradiation.
