This research investigates the electronic properties of a fungi-derived pigment, xylindein
as a novel sustainable material for organic electronics. Xylindein molecules were characterized in solution and in film. Absorption spectra and (photo)luminescence spectra were
taken at various excitation wavelengths. Xylindein’s molecular properties were computed
with the Gaussian 09 software suite. Pentacene and peri-xanthenoxanthene were used as
references for the reliability of the computations. Thin film devices were made to measure
the (photo)conductivity at various excitation wavelengths and current-voltage data. Experimental results for anthradithiophene were used for comparison. A lower limit for the
charge carrier mobility was estimated to be 0.5 cm²/(V s). Xylindein shows promise for use in both single-component and donor/acceptor solar cells.
