A High-Capacity Semiconductor Organic Polymer for Stable Aqueous Ammonium-Ion Storage.

ABSTRACT: In aqueous ammonium-ion storage (AAIS), effective hydrogen-binding sites are crucial for designing high-performance ammonium ions (NH₄ ⁺) host materials. The organic small molecule tetraamino-p-benzoquinone (TABQ) shows great potential in AAIS due to its unique hydrogen-bonding interactions with NH₄ ⁺. However, such small-molecule materials typically exhibit severe dissolution in aqueous electrolytes. Moreover, their low conductivity severely hampers their ability to store ammonium ions. To address these challenges concurrently, a chain amide polymer (PPAT) is designed by introducing a 3,4,9,10-perylenetetracarboxylic dianhydride to extend the skeleton of TABQ. This polymer exhibits an ultralow solubility of 0.00058 mg mL^-1 and introdu
