A novel cuprous coordination polymer built of [Cu 4 I Cl] cluster and 4‐(1,2,4‐triazol‐4‐yl)phenylphosphonate acid (H 2 ptz) ligand has been hydrothermally synthesized, in which the Cu I is in‐situ generated by the reduction reaction from Cu II precursors. This compound shows a green fluorescent emission with a maximum peak at 510 nm under N 2 flow in solid state, which can be turned off by 21 % O 2 flow in minutes. Interestingly, it can be turned on again by switching to N 2 flow. A possible mechanism has also been proposed.
