Abstract
A new family of tetracene tetracarboxylic diimides is provided. These ones can made by reacting a 9-stannafluorene with a tetrabromo compound including a tetracene tetracarboxylic diimide core. They can be used as n-type electron-transporting materials in electronic devices such as n-channel field-effect transistors. They exhibit excellent air-stability and do not cause parasite injections of holes.
