Preparation of Ruthenium Dithiolene Complex/Polysiloxane Films and Their Responses to CO Gas.

ABSTRACT: To develop advanced materials using metal complexes, it is better to prepare metal complexes contained in composite or hybrid films. To achieve this purpose, we synthesized ruthenium complexes with dihalogen-substituted benzendithiolate ligands, [(η⁶-C₆Me₆)Ru(S₂C₆H₂X₂)] (X = F, 3,6-Cl, Br, 4,5-Cl), 1b-1e. We also investigated preparation of 1c or 1e containing polysiloxane composite films and their reactivity to CO gas. All ruthenium complexes 1b-1e reacted with CO gas, and carbonyl ligand adducts 2b-2e were generated. Ruthenium complexes 1b-1e show two strong absorption peaks around 550 and 420 nm. After exposure to CO gas, these absorption peaks were immediately decreased without a peak shift. A similar trend was obser
