Paper Abstract

We present photophysical and optoelectronic properties of xylindein and optical properties of two other fungi-derived organic pigments. Photophysics of these materials is determined by the interplay of inter- and intramolecular hydrogen bonding, which was systematically explored using absorption and photoluminescence spectroscopy of xylindein in various solutions, pH buffers, and in the solid state. Amorphous xylindein films yielded a lower bound on the charge carrier mobility of 0.2-0.5 cm2=(V•s) and exhibited photocurrent upon photoexcitation in the ultraviolet and visible wavelength range. Thermal and photostability of xylindein was also characterized, and it considerably exceeded that of conventional organic semiconductors such as pentacene derivatives.
