The unimolecular reactivities of a range of perbenzoate anions (X−C6H5CO3-), including the perbenzoate anion itself (X = H), nitroperbenzoates (X = para-, meta-, ortho-NO2), and methoxyperbenzoates (X = para-, meta-OCH3) were investigated in the gas phase by electrospray ionization tandem mass spectrometry. The collision-induced dissociation mass spectra of these compounds reveal product ions consistent with a major loss of carbon dioxide requiring unimolecular rearrangement of the perbenzoate anion prior to fragmentation. Isotopic labeling of the perbenzoate anion supports rearrangement via an initial nucleophilic aromatic …

Electroactive polymers can be engineered at the molecular level to recognise external stimuli, they are conductive and they are capable of localised processing. These are properties which make them ideal building blocks for intelligent materials. This article investigates the suitability of carbon nanotubes of enhancing (polymer) building blocks for intelligent materials.
