Calix[4]arene Derivative for Iodine Capture and Effect on Leaching of Iodine through Packaging.

ABSTRACT: A hydrophobic calix[4]arene derivative was investigated for its iodine (I₂) capture efficiency from gaseous and liquid phase. The iodine uptake was followed by UV-vis spectroscopy. Additionally, the influence of the calix[4]arene derivative-polyolefin system on the leaching of iodine through packaging from a povidone-iodine-based (PVP-I) formulation was evaluated. In fact, iodine is a low-cost, multi-target, and broad-spectrum antiseptic. However, it is volatile, and the extended storage of I₂-based formulations is challenging in plastic packaging. Here, we investigated the possibility of reducing the loss of I₂ from an iodophor formulation by incorporating 4-tert-butylcalix [4]arene-tetraacetic acid tetraethyl ester (CX) and its iodine complex in hi
