Abstract
  • In industry, there is considerable interest in finding sustainable, renewable materials for use in electronic devices. Pigments derived from spalting fungi are of particular interest due to their longevity in diverse environmental conditions. The focus of my project was to characterizethe properties of a novel, fungi-derived pigment, and to discover any interesting characteristics of the pigment produced by ​Scytalidium ganodermopthorum​. The pigment has an effective carrier mobility two orders of magnitude less than the leading fungi-derived pigment xylindein. It shows yet unexplained reactions to long term exposure to light, appearing to change structure while bleaching over time. Additionally, it has shown to crystallize for the first time upon evaporation from dichloromethane. This preliminary study concluded that the electronic properties of the pigment require further experimentation, and displayed interesting characteristics warranting further study in other applications.
