Fig. 1

(A) Schematics comparing the microstructures of pristine SY and is-EMLs designed in this study. (B) Mechanical properties of pristine SY and is-EML thin films. (C) Carrier mobility of pristine SY and is-EMLs measured through the hole- and electron-only devices. (D) Tg of pristine SY and is-EMLs measured by DMA. (E) UV-vis absorption spectra of pristine SY and is-EMLs. On the basis of the various analysis results, by adding Triton X into SY, the SY chains become extended. Hence, a fibrillar microstructure with elongated domains is formed, which is favorable for stretchable electronics.
