Phenanthrenes, a polycyclic aromatic hydrocarbon (PAH) molecule, widely presented in natural products [1], pharmaceuticals [2], and material sciences [3]. For instances, representative compounds I–IV have biological and pharmacological activities, such as anti–cancer, anti–fungal, anti–inflammatory and anti–psychotic properties (Fig. 1) [4]. Phenanthrenes show good electrochemical and photochemical properties because of the effect of extended π–conjugated systems [5].
