Synthesis of a tetrabenzotriazacorrole μ-oxo dimer and investigation of its stacking effect†
Abstract
A μ-oxo dimer of phosphorus(V) tetrabenzotriazacorrole (PTBC) has been synthesized and characterized for the first time. Spectroscopic and theoretical analysis support the opinion that two PTBC chromophore groups interact with each other, while the low-symmetric PTBC structure is also efficient for generating singlet oxygen.
