Application

Pyrrole is used as one of the building blocks of biochemical macrocycles such as chlorins, porphyrins and corrins. It is also used for many technologically relevel applications such as in organometallic complexes and precursor molecules for self-assembled monolayers on metal surfaces.

Calix[4]pyrroles offer a great potential as stationary phases for gas chromatography (GC) due to their unique structures and physicochemical properties. Herein we present the first report of using two calix[4]pyrroles, namely meso-tetra-cyclohexylcalix[4]pyrrole (THCP) and meso-octamethylcalix[4]pyrrole (OMCP). These stationary phases were
