Extended Data Fig. 3: EL performance of the rigid OLED devices with PDKCD as the emitting layer under different strains.
From: High-efficiency stretchable light-emitting polymers from thermally activated delayed fluorescence

(a) Representative EQE-current density plots. (b) Averaged EQEmax values as a function of different strains. The data of EQE are represented as mean values + /− s.d. from 3 devices. (c) Representative EL spectra at 8 V.
