Abstract: In this paper, a new discrete coordination metallacycle complex, [CuI(bipy)]2 (1), is synthesized by solvothermal method using 2,6-bisimdazol pyridine and cuprous iodide as starting materials. The X-ray diffraction structure, temperature-dependent electronic absorption and photoluminescence spectra have been investigated. The solid-state fluorescence at variable temperatures shows that complex 1 exhibits an obvious thermochromic fluorescence. At low temperature, the dual fluorescence with peak at 590 and 694 nm was observed. The emission color significantly changes from red at 77 K to yellow at 200 K and blue-green at 330 K. The thermochromic fluorescent molecular materials shows great potential as temperature sensing.
