Newly Synthesized High‐ <i>k</i> Polymeric Dielectrics with Cyclic Carbonate Functionality for Highly Stability Organic Field‐Effect Transistor Applications

Organic field-effect transistors (OFETs) with low-voltage-operating high-stability are regarded as one of the key components future electronics. However, it remains a challenge to enhance bias–stress stability, mechanical durability and environmental adaptability while reducing operating voltage flexible OFETs. In this study, new strategy introducing high-dipole-moment groups into polymer side chains intensity polarization was proposed. This can redirect cyclic carbonate high-dipole under action electric fields realize stable operation efficient charge transfer. The experiments showed that high-performance OFETs were mainly attributed synthesized polymers through molecular structure designing which not only have high dielectric constant (k > 5) electrical insulating property but also favor growth organic semiconductor films. still excellent flexibility, electrical, thermal humidity stability. addition, highly applied floating-gate memory fullerene (C60) embedded layer an integrated one-transistor-one-transistor cell. They exhibited performance large window (8.5 V), current ratio (103), retention (2 × 104 s), endurance (200 cycles), multi-level (over 4 levels) non-destructivity.
