The continuous exploration of new analogs of calixarenes and pillararenes unlocks infinite opportunities in supramolecular chemistry and materials. In this work, we introduce a new class of macrocycle, phenyl‐extended resorcin[4]arenes (ExR4), a unique and innovative design that incorporates unsubstituted phenylene moieties into the resorcin[4]arene scaffold. Single‐crystal analysis reveals a chair‐like conformation for per‐methylated ExR4 (Me‐ExR4) and a twisted "figure‐of‐eight" shaped conformation for per‐hydroxylated ExR4 (OH‐ExR4). Notably, OH‐ExR4 demonstrates exceptional adsorption capability toward I3− ions in an aqueous solution, with a rapid kinetic rate of 1.18×10‐2 g·mg‐1·min‐1. Furthermore, OH‐ExR4 shows excellent recyclability and potential as a stationary phase in column setups. The discovery of ExR4 opens up new avenues for constructing new macrocycles and inspires further research in functional adsorption materials for water pollutant removal.

Bromine (Br2) and related species removal from water systems are rather complicated due to the complicated chemistry instability, and materials with high Br2 removal rate and efficiency, along with stimuli/apparatus suitable for highly corrosive environments, are necessary. Ultrasonication as a non‐destructive process is especially suitable in scenarios where conventional stir apparatus is not applicable, such as highly corrosive environments. Considering the validity nature of Br2 and combining the advantages of ultrasonic with a highly stable Br2 fixation method through aromatic polymer nanoparticles, we demonstrate highly efficient acoustic‐aided Br2 removal in aqueous solutions with two times capacity compared to the non‐treated sample. Related aquatic applications are also proposed for the materials to be cost‐effective, including silver (Ag) recovery, recyclable MnO2‐mediated Br2 deep removal, and aqueous zinc anode modification. The coupled novel‐material‐based processes motivate the strategic design of water purification with high‐safety and sustainable industrial procedures and post‐value‐added utilizations.
