Cure monitoring of a photosensitive polymer using the luminescent organometallic complex fac-CIRe(CO)3(4,7-Ph2-phen)

Abstract The organometallic complex fac-CIRe(CO) 3 (4,7-Ph 2 -phen) exhibits a bright yellow-orange phosphorescence centred at 576 nm in poly(methyl methacrylate)/trimethylolpropane triacrylate (PMMA/TMPTA) solutions. This luminescence feature is shown to be a useful spectroscopic probe of the acrylate crosslinking reactions in the u.v. photochemical curing of a model PMMA/TMPTA thin film system.
