摘要：

Supercritical CO2 (scCO2) is used to impregnate high density polyethylene film with [(C5Me5)Ir(CO)2]; UV irradiation causes changes in the IR spectrum consistent with C-H activation and formation of [(C5Me5)Ir(CO)(H)(polymer)], and subsequent extraction of the polyethylene with scCO2 removes unreacted [(C5Me5)Ir(CO)2] leaving the photoproduct in the film.
