p-Phenylcalix[4]arene is formed directly from p-phenylphenol in 66% yield (50% isolated yield) using poly(ethylene glycol) as the reaction medium, with crystallization of the pure cavitand from toluene mediated by p-carborane. The solid-state structure comprises interlocking columnar arrays.

In this study chitosan/poly(ethylene glycol)-ran-poly(propylene glycol) blend was developed as separator and binder for supercapacitor (SC) applications. The activated carbon (ACTS-900) derived fromTamarindus indicaseeds is used as active electrode material.
