Degradable Donor‐Acceptor Polymeric Mixed Ionic‐Electronic Conductors for Transient Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
Here, we report degradable donor–acceptor (D–A) polymeric mixed ionic‐electronic conductors for transient electronics. We take a systematic side chain engineering approach to elucidate how molecular‐level modifications of donor–acceptor (D–A) polymer structures can satisfy demands that are often conflicting: degradability, charge carrier transport, and
