Extended Data Fig. 4: Snapshots taken from the MD simulations of PDKCM, PDKCP, and PDKCH at 0% and 100% strains.
From: High-efficiency stretchable light-emitting polymers from thermally activated delayed fluorescence

One randomly selected chain is highlighted for each simulation and manually centred at the middle of the box, with the backbone rendered in grey, the electron-donor units in blue, and the electron-acceptor units in red.
