While the fascinating field of soft machines has grown rapidly over the last two decades, the materials they are constructed from have remained largely unchanged during this time. Parallel activities have led to significant advances in the field of dynamic polymer networks, leading to the design of three‐dimensionally cross‐linked polymeric materials that are able to adapt and transform through stimuli‐induced bond exchange. Recent work has begun to merge these two fields of research by incorporating the stimuli‐responsive properties of dynamic polymer networks into soft machine components. These include dielectric elastomers, stretchable electrodes, nanogenerators, and energy storage devices. In this Minireview, we outline recent progress made in this emerging research area and discuss future directions for the field.

“…The influence of photoselection artefacts or anisotropy of the system in the measured ECD and FDCD spectra at higher concentrations were evaluated by measuring the linear polarization components, i.e. linear dichroism (LD) 77,78 and linear birefringence (LB) 78,79 in case of ECD, and fluorescence-detected linear dichroism (FDLD) 38,80 in case of FDCD (Fig. S39-S40 †).…”

Fluorescence detected linear dichroism of small molecules oriented on polyethylene film

Abstract: We demonstrate that by measuring the fluorescence emission data during a linear dichroism measurement, one obtains additional information on the exited state properties and interactions of oriented molecules in the solid state.
