abstract The 1-tetrazole-4-imidazole-benzene (HL) used as a tetrazole-functionalized spacer constructs 3-D [Cu-2(mu(3)-I)(L)](n) (1) with longer Cu center dot center dot center dot Cu distances to eliminate the existence of cuprophilic interaction. 1 shows important thermochromic luminescence and its emission maximum exhibits a gradual red shift with increasing temperature, indicating that 1 is a potential application for a luminescent thermometer with a wide range. Of particular interest, the thermochromic luminescent properties of the reported Cul-tetrazolate systems have not been investigated, while this work first reveals that Cul-tetrazolate system without cuprophilic interaction generates remarkable thermochromic luminescence. Moreover, 1 exhibits selectively photocatalytic degradation of methylene blue (MB) under UV light irradiation, and its density functional theory calculation has also been performed.
