Electron‐injected BN nanotubes with high specific surface area (HS‐BNNTs) were prepared through bonding with a monolayer of zinc phthalocyanine (ZnPc) molecules (see TEM image). Strong interactions between ZnPc and the HS‐BNNTs not only modify their ground‐state electronic structures, but also lead to striking intramolecular photoinduced charge transfer. The functionalized HS‐BNNTs may be of high value in photochemical and photoelectrical devices.
