Hybrid materials composed of zinc phthalocyanines (ZnPcs) and BN nanotubes (BNNTs) (see figure) exhibit interesting electronic interactions. The efficient charge separation of these systems is characterized with the aid of an electron mediator, methyl viologen (MV). Photoinduced charge transfer from ZnPc to the BNNTs makes these novel hybrids promising photosensitized charge-separation/electron-mediating systems.
