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.
