9. 4/PVPK solution (0.2 mL) was deposited on a microscope slide, and the solvent was allowed to evaporate in air. Once the film had adhered, the slide was placed in a PL cell and the film was dried under vacuum for 2-4 h.
10. The glass slide bearing the film was mounted inside a Schlenk luminescence cell. The film was excited with 0.5-3.0 mW of 488-nm light from a Coherent Innova 90-4C Ar ion laser. Emission was monitored with an Oriel Multispec 77400 CCD detector via fiber optic probe. For each experiment the emission profile was recorded, and the PL intensity at the emission maximum (575 nm) was monitored in response to changes in the ambient atmosphere of the film. Conditions tested were 1 atm Ar and air, vacuum, and pressures of ethylene ranging from 0 to 760 Torr. There was no change in the maximum emission wavelength in any experiment.
11. 3CN-cast films, 1 cycle over 1 h for THF-cast films), until the emission under vacuum was constant.
12. Conditioned films were exposed to varying pressures of ethylene, and the PL response was measured. Reversible and proportional responses were also observed for propylene. Stern-Volmer analysis was performed according to Lakowicz (Lakowicz, J. R. Principles of Fluorescence Spectroscopy, 2nd ed.; Kluwer Academic/Plenum Publishers: New York, 1999). Data were analyzed with the IGOR Pro graphical analysis program.
13. 4-PVPK functional groups were prepared on NaCl plates in a drybox. The film-bearing plate was mounted in an IR cell designed for facile exchange of the ambient gas atmosphere. IR spectra were recorded on a Brucker Equinox 55 FT-IR spectrometer; the spectra reported are averages of 32 scans. The film was conditioned by cycling between vacuum and 700 Torr ethylene. All spectra were recorded under vacuum except the spectrum of the ethylene-exposed film, which was recorded after ethylene had been flushed from the cell with a constant flow of argon for ca. 10 min.
