Subphthalocyanines: contracted porphyrinoids with expanded applications

Subphthalocyanines (SubPcs) have undergone extensive research activity be-cause of their unique properties, rich chemistry, and tremendous applicability. Over decades, researchers have achieved substantial progress in understanding the molecular structure-property relationship of SubPcs, as well as in imple-menting them in state-of-the-art technological devices. However, more than 50 years after their discovery SubPcs are still far from unleashing their full poten-tial. In this short review, we disclose the main trends in SubPc chemistry, with particular attention focused on their use as molecular materials.
