Abstract
Fluorescence Probe Technology (FPT) is a recently developed method, which offers a possibility of online applications for monitoring of polymerization processes by means of appropriate fluorescent molecular probes that change their fluorescence characteristics upon changes occurring in their environment. Depending on the type of the process monitored and the monitored parameters, appropriate structure and characteristics of the probe are required. Therefore, development of new probes and/or identification of the probes suitable for particular systems among fluorophors available commercialy is important for their practical applications. In this research applicability of 2-amino-4,6-diphenyl-pyridine-3-carbonitrile derivatives as molecular probes for monitoring photoinitiated free-radical and thiol-ene polymerization of multifunctional monomers is reported. The progress of the photo-polymerization was monitored using a specially designed cure monitoring system, and fluorescence intensity ratios as the progress indicator. Relative kinetic parameters were determined from the kinetics profiles. It has been found that all of the 2-amino-4,6-diphenyl-pyridine-3-carbonitrile derivatives shifted their fluorescence spectra towards shorter wavelengths with polymerization progress, which was critical for application of these fluorophores as fluorescent probes.
