Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

Advanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

Heterogenized Copper(II) Phenanthroline Catalysts for Electroreduction of CO2 to C2 Compounds: Substitution on the Ligand Causes Structural Changes to the Molecular Framework and Stability Enhancement

Advanced Materials, EarlyView.
Based on a previously reported binuclear Cu(II) phenanthroline catalyst, a structurally modified version with enhanced stability for electrochemical reduction of CO2 is developed. The second‐generation system allows for stable operation in an MEA electrolyzer with a Faradaic efficiency of >70% for C2 products at elevated current densities.
