The emergence of wearable technology can significantly benefit from electronic displays fabricated using intrinsically stretchable (is-) materials. Typically, an improvement in the stretchability of conventional light-emitting polymers is accompanied by a decrease in charge transportability, thus resulting in a significant decrease in device efficiency. In this study, a self-assembled 3D penetrating nanonetwork is developed to achieve increased stretchability and mobility simultaneously, based on high-molecular-weight phenylenevinylene (L-SY-PPV) and polyacrylonitrile (PAN). The mobility of L-SY-PPV/PAN increases by 5-6 times and the stretchability increases from 20% (pristine L-SY-PPV film) to 100%. A high current efficiency (CE) of 8.13 cd A-1 is observed in polymer light-emitting diodes (PLEDs) fabricated using 40% stretched L-SY-PPV/PAN. Furthermore, using a polyethyleneimine ethoxylated (PEIE), an 1,10-phenanthroline monohydrate (pBphen), and a reduced Triton X-100 (TR) chelated Zn-based is- electron-injection layer of Zn-PEIE-pBphen-TR, an is-PLED is realized with a turn-on voltage of 6.5 V and a high CE of 2.35 cd A-1 . These results demonstrate the effectiveness of using the self-assembled 3D penetrating nanonetwork for the fabrication of is-PLEDs
