CO‐catcher : Carbon monoxide can be detected selectively and sensitively by the binuclear rhodium complex cis ‐[Rh 2 (C 6 H 4 PPh 2 ) 2 (O 2 CCH 3 ) 2 ](HO 2 CCH 3 ) 2 . This complex, which contains two cyclometalated phosphine ligands, coordinates CO axially and undergoes a color change from violet to orange‐yellow (see picture).
