Abstract
A photoluminescent polymer/transition metal complex is disclosed which is capable of selectively binding to alkenes to thereby alter the photoluminescence of the complex. In one embodiment, a poly(vinyl phenyl ketone)/Ag(I) complex is disclosed which reversibly and selectively binds with ethylene. The disclosed photoluminescent polymer/transition metal complex can be used as part of a sensor to determine the presence and/or concentration of alkenes such as ethylene.
