title: Semiconductor properties of melanins prepared from catecholamines.
abstract: D. C. dark - and photoconductivity measurements were performed with synthetic melanins prepared by oxidative polymerization of dopamine, adrenaline, adrenochrome and adrenolutin. The melanins examined show significant differences in conductivity, thermal activation energy and photocurrent intensity values. The differences in semiconductor properties observed between the melanins reflect the structure differences of catecholamine-melanin polymers.
