摘要：

Perylene tetracarboxylic acid bisimide, in short perylene bisimide (PBI) based colorants have received a considerable attention in academic as well as industrial dye and pigment research. Since PBIs are known as the best n-type semiconductors available to date, there have been a lot of effort to use them as electronic materials. This <<-type semi-conductivity is related to the high electron affinity of rylene bisimide dyes which makes naphthalene, perylene, as well as higher rylene bisimide dyes most promising for application in organic field effect transistors. In addition, based on their unique combination of optical and electrochemical properties with outstanding stability, PBI dyes have already been investigated extensively for more than a decade in electrophotography (xerographic photoreceptors) and photovoltaics.
