Wavelength‐Dependent Photochromic Inorganic–Organic Hybrid Based on a 3D Iodoplumbate Open‐Framework Material

Plumb pudding: A 3D iodoplumbate inorganic–organic hybrid built from purely octahedral units, obtained through in situ solvothermal synthesis, belongs to a new structural subclass of organically templated inorganic open-framework materials. It exhibits the properties of its 1D incomplete-cubane-chain building block and shows ordered and periodic quantum-wire behavior, as well as a wavelength-dependent photochromic response.
