Self‐Doped Perylene Diimide‐Based Polymers for Simultaneous Improvements in Efficiency and Thermal Stability of Organic Solar Cells

open access: yesSmall, EarlyView.
PPV‐M, an amorphous electron transporting polymer with a high Tg of 118°C, suppresses thermally induced molecular diffusion in organic solar cells. Unlike crystalline PDINN (Tg = 61°C) with a T80 of only 8 h, PPV‐M maintains efficient electron extraction and extends T80 to 637 h, representing an 80‐fold enhancement in thermal stability.

Highly integrated, alignment healing, and full‐recyclable multifunctional flexible devices based on dynamic covalent bonds

open access: yesSmart Molecules, EarlyView.
This study addresses stability, repair, and recycling in flexible devices using polymers with identical dynamic bonds but incompatible backbones. This enables robust integration, precise self‐healing, and full recyclability. We demonstrate optoelectronic sensors that, after damage, magnetically self‐assemble and heal upon heating.
