Extended Data Fig. 1: Optical microscopy images of PDKCM, PDKCP, DDKCH, and PDKCD films under stretching to the strains of 50%, 75%, and 100%.
From: High-efficiency stretchable light-emitting polymers from thermally activated delayed fluorescence
The films were transferred from PDMS substrates to SEBS-coated Si substrates. The stretching direction was horizontal.
