A luminescent Cu<sub>2</sub>I<sub>2</sub>P<sub>2</sub>S<sub>2</sub>-type binuclear complex and its fluorescence sensing for pyridine
Luminescent Cu<sup>I</sup> complexes are an important class of coordination compounds due to their relative abundance, low cost and ability to display excellent luminescence. The title Cu<sub>2</sub>I<sub>2</sub>P<sub>2</sub>S<sub>2</sub>-type binuclear complex, di-μ-iodido-bis[(thiourea-κS)(triphenylphosphine-κP)copper(I)], [Cu<sub>2</sub>I<sub>2</sub>(CH<sub>4</sub>N<sub>2</sub>S)<sub>2</sub>(C<sub>18</sub>H<sub>15</sub>P)<sub>2</sub>], conventionally abbreviated as Cu<sub>2</sub>I<sub>2</sub>TPP<sub>2</sub>TU<sub>2</sub>, where TPP and TU represent triphenylphosphine and thiourea, respectively, is described. In this complex, each Cu<sup>I</sup> atom adopts a CuI<sub>2</sub>PS four-coordination mode and pairs of atoms are connected to each other by two μ<sub>2</sub>-I ligands to form a centrosymmetric binuclear cluster. It was also found that the paper-based film of this complex exhibited obvious luminescence light-up sensing for pyridine and 4-methylpyridine.
