Abstract:

Benzene-1,3-dicarboxylic acid(H2BDC) and 5-hydroxy-1,3-benzene dicarboxylic acid(H2OIP) have been employed to synthesis two organic-inorganic hybrid arsenomolybdates, (NH417H4[(AsMo6O212(AsMo6O23)(BDC)4]·28H2O(1) and (NH45Cs8H6[(AsMo6O213(OIP)5]·40H2O(2). X-Ray crystallographic study indicated that both of the two compounds are trimers. The photochromic properties have been studied. Under the irradiation of a Xe-lamp, the two compounds changed their colors within 5 min. The thermochromic study of the two compounds indicated that they changed color at 373 K, and their color deepened on the increase of temperature.

Key words: Hybrid polyoxometalate, Hetero-arsenomolybdates, Aromatic dicarboxylic acid, Photochromic property
