Vanadosilicate zeolite AM‐6, which contains a 3D array of vanadate (V IV O 3 2− ) quantum wires (see picture), was prepared as high‐quality crystals (free from V V , titanosilicate seeds, and pore‐blocking organic template cations) from inexpensive V 2 O 5 . The linear dependence of λ max and band‐gap energy E g on the partial charge on the framework O atoms reveal that the UV band of AM‐6 is due to V IV ‐to‐O metal‐to‐ligand charge transfer.
