Article Synopsis
- Kang, Sigler, Lee & Yun is a destructive fungus that produces a yellow pigment useful for sustainable products, but its decay abilities haven't been well-studied.
- Testing on wood blocks revealed inconsistent pigment production and soft rot characteristics, showing cell wall damage but lacking certain enzymes typically associated with decay.
- The findings imply that growing the fungus in liquid media is more effective for achieving reliable yellow coloration than using it on wood substrates.
Organic 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. Herein, femtosecond transient absorption spectroscopy with a near-IR probe was used to unveil a rapid excited-state intramolecular proton transfer reaction.

Recently, natural product-derived organic pigments attracted attention due to their extraordinary environmental stability and unexpectedly good optoelectronic performance, in spite of only partially conjugated molecular structure. Fungi-derived pigments are a naturally sourced, sustainable class of materials that are largely unexplored as organic semiconductor materials.
