General Description [12]Cycloparaphenylene ([12]CPP) is a macrocyclic hydrocarbon with a circular structure formed by 12 para-linked benzene rings, as confirmed by X-ray crystallography, which also revealed its ability to encapsulate two cyclohexane molecules within its cavity. Its synthesis involves nickel-mediated macrocyclization or selective preparation via platinum intermediates. The electronic properties of [12]CPP, such as NMR shifts and redox behavior, are influenced by its ring size, with larger CPPs exhibiting higher-field proton shifts and higher oxidation potentials compared to smaller analogues. Fluorescence spectra are notably size-dependent, though UV-vis absorption remains less sensitive. These findings highlight the unique structural and electronic characteristics of [12]CPP within the cycloparaphenylene family.
