Advanced Science, EarlyView.Here, we propose a single‐crystal PZT‐based piezo‐phototronic organic adaptive memory transistor (OAMT), achieving a record memory window capacity factor (γ) of 0.87 at a low SS of 200 mV/decade via efficient multi‐field control. The device achieves a high recognition accuracy ∼ 90% in neuromorphic simulations, demonstrates robust fault tolerance under

Advanced Science, EarlyView.A series of photo‐responsive polymers are prepared by a facile one‐pot in situ synthesis strategy, where RTP modules and photochromic units are systematically integrated into one polymer system. The triplet‐singlet Förster resonance energy transfer (TS‐FRET) between the donor and acceptor enables the material to exhibit time‐dependent phosphorescence ...
