One-Pot Synthesis of Stable NIR Tetracene Diimides via Double Cross-Coupling
摘要:
Tetracene tetracarboxylic diimides have been synthesized based on direct double ring extension of electrondeficient naphthalene diimides involving metallacyclopentadienes. Atomic structure and electronic transitions responsible for their NIR absorption spectra are investigated with quantum-chemical calculations. In light of their unique structure and admirable photophysical and electronic properties, this new molecular skeleton is promising candidate for n-type semiconductors.

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.
