Vinyl polymers are appealing materials owing to their ease of synthesis and broad diversity. Their carbon–carbon backbones resist degradation, however, which limits the applications for which they can be used. This Review Article considers the most promising approaches to the design of degradable vinyl polymers and discusses the potential of these materials for biomedical applications.
Ferroelectric materials hold much promise for the development of devices such as nonvolatile memories, sensors and nonlinear optic materials. This Review describes the molecular features required to devise organic molecular ferroelectrics, and presents the supramolecular chemistry strategies available for controlling molecular organization and dynamics across different length scales.
Bringing porphyrins in contact with well-defined interfaces generates a rich playground of chemical behaviour and properties for exploration and exploitation. This Review examines our current understanding of surface-confined tetrapyrroles and their embedding in nanoarchitectures - discussing both the structural and functional attributes, and methods by which to manipulate their intramolecular and organizational features.
