Two-photon excitable boron complex based on tridentate imidazo[1,5- a ]pyridine ligand for heavy-atom-free mitochondria-targeted photodynamic therapy.

We have synthesized a cyan fluorescent boron complex based on a tridentate imidazo[1,5- a ]pyridine ligand. The boron complex was found to have potential applications as not only a chiroptical material but also a heavy-atom-free mitochondria-targeted photosensitizer for cancer treatment.
