In recent years, there has been a renewed interest in the study of open-shell polycyclic
aromatic hydrocarbons (PAHs). Among them, biradicals exhibit attractive electronic,
magnetic and optical properties which make them promising candidates for a wide
range of applications in organic electronics, such as nonlinear optics, molecular
spintronics, energy storage and organic photovoltaic devices sensitized by singlet
fission. Despite all the promising properties of open-shell PAHs, a common drawback
still needs to be overcome: the high reactivity of radicals, which implies that most
open-shell species tend to be too short-lived for practical aplications and even for
characterization [1]. In this regard, Raman spectroscopy has shown to be a suitable tool
for studying this kind of molecular systems, being able to provide valuable information.
This work reports the study of a new biradical, diindeno[b,i]anthracene (DIAn)[2], [3]
,
highlighting the crucial role played by Raman Spectroscopy in the characterization of
the ground electronic state as well as in the rationalization of the ambipolar behavior
shown in OFETs. To this end, neutral and charged species has been studied by Raman
spectroscopy as a function of excitation wavelength, temperatura and pressure.
