Abstract
► Optical absorption spectrum of monocation radical of pentacene is measured by charge-modulation spectroscopy. ► Charge-modulation spectroscopy was applied to vacuum-sublimed films of pentacene in the MIS diode configuration. ► The spectrum exhibited several peaks in the wavelength range of 300-800 nm. ► The signal in the visible was ascribed to the field-modulation effect of a neutral pentacene film, while the three broad peaks in the UV were ascribed to the optical absorption due to a monocation radical of pentacene. ► This assignment was supported by the theoretical calculations reported earlier.
