Methodology for the radiation hardness assessment of organic semiconductors

The first systematic study of the radiation hardness of a series of structurally similar conjugated polymers, model organic semiconductors, involves the set of numeric descriptors for quantitative benchmarking of their stability under exposure to the ionizing radiation. The conjugated polymers demonstrate surprisingly high radiation hardness and can tolerate huge doses of gamma rays up to 16 MGy much better than commodity types of plastic, which opens opportunities for their application in the development of radiation-tolerant organic electronics.
