Tetrachloro‐substituted Perylene Bisimide Dyes as Promising n‐Type Organic Semiconductors: Studies on Structural, Electrochemical and Charge Transport Properties

Twisted π-systems: The highly twisted 1,6,7,12-tetrachloro-substituted perylene bisimides possess an improved electron affinity. The nonplanar nature of these molecules facilitates a slipped brickstone-type rather than a columnar stacking of the π-systems, with a potentially useful two dimensional contact feature. These compounds show isotropic charge carrier mobilities as high as up to 0.14 cm2 V−1 s−1 (see graphic).
