Use of 3-hydroxyflavone as a fluorescence probe for the controlled photopolymerization of the E-Shell 300 polymer

Moreover, time-resolved measurements of the emission lifetimes showed significant difference between 3-HF emission lifetime in low viscous solvent (0.9 ns)) and in polymerized sample (3.2 ns)) which also can be applied in control of photopolymerization. 3-HF is a relatively cheap, non-toxic and has good solubility in the polymer media we chose.
