Extended Data Fig. 1: Density functional theory (DFT) optimized structures, HOMO, and LUMO distributions for the repeating units of stretchable ETL polymers.
From: Enabling efficient electron injection in stretchable OLED
a, The molecular structure of the stretchable ETL polymers. The conjugated tri-repeating unit is in the blue dashed frame, while the non-conjugated repeating unit is in the red dashed frame. b, The optimized structure, HOMO, and LUMO distributions for the conjugated tri-repeating unit of the stretchable ETL polymers. c, The optimized structure, HOMO, and LUMO distributions for the non-conjugated repeating unit of the stretchable ETL polymers.
