Advanced Materials, EarlyView.A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

Poly(Alkoxythiophene) Rod‐Coil Block Copolymers for Organic Electrochemical Transistors
Advanced Materials, EarlyView.We present the first synthesis of poly(3‐alkoxythiophene) rod‐coil block copolymers as a new architecture for OMIECs. Incorporating PEG and PLLA coils can enhance device performance beyond the homopolymer. The figure‐of‐merit depends uniquely on coil length.

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid
Advanced Materials, EarlyView.Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.
