Determination of the Stern-Volmer constant in benzene solution of the poly(vinyl phenyl ketone)—trans-Stilbene system: Comparison between the HPLC and viscometric techniques
The energy transfer evaluation of poly(vinyl phenyl ketone) (PVPK) as a polymeric photosensitizer has been carried out following two different procedures: by monitoring the trans → cis isomerization of stilbene by quantitative analysis of cis-stilbene with High Performance Liquid Chromatography (HPLC) and by viscometric measurements of the course of the reaction. The Stern-Volmer constants (ksv) afforded by the HPLC and viscometric methods, 88 and 92m−1 respectively, show a good concordance.
