Honey as a Growth Medium for Sustainable Fungal-based Pigments

open access: yes
Fungi in the Chlorociboria genus produce a blue pigment called xylindein—a pigment historically used to color wood for marquetry and now under investigation as a thin film for photovoltaic cells. The pigment’s value comes from its unusual characteristics,

The structure of xylindein [PDF]

open access: yesTetrahedron, 1965
Abstract Xylindein has been isolated from infected wood and several new derivatives have been prepared. Spectroscopic examination of xylindein and its derivatives has established the orientation of the substituents on the central peri-xanthenoxanthene nucleus which has been identified by a mass spectral analysis of the zinc dust distillation product.

Ultrafast Dynamics and Photoresponse of a Fungi-Derived Pigment Xylindein from Solution to Thin Films

open access: yesChemistry - A European Journal, 2021
AbstractOrganic semiconductor materials have recently gained momentum due to their non‐toxicity, low cost, and sustainability. Xylindein is a remarkably photostable pigment secreted by fungi that grow on decaying wood, and its relatively strong electronic performance is enabled by π–π stacking and hydrogen‐bonding network that promote charge transport.

Fungi-derived xylindein: effect of purity on optical and electronic properties

MRS Advances, 2019
We present a study of optical and electronic properties of solutions and films based on the fungi-derived pigment xylindein, extracted from decaying wood and processed without and with a simple purification step (“ethanol wash”). The “post-wash” xylindein solutions exhibited considerably lower absorption in the ultraviolet spectral range and ...
