Photochromic inorganic-organic hybrid: a new approach for switchable photoluminescence in the solid state and partial photochromic phenomenon

A photochromic inorganic-organic hybrid based on in situ generated MV2+ cation (MV2+ = methyl viologen = N, N'-dimethyl-4,4'-bipyridinium) has been obtained, in which a vagarious partial photochromic phenomenon together with its photoluminescence modulation properties are reported for the first time in the inorganic-organic hybrids.
