Two water soluble benzophenone sensitizexs are examined through measurements of UV,phosphorescence spectra, quantum yields,liftime of phosphorescence and transient absorption of flash photolysis. It has been found that the OH group in the side chain of sensitizer has a great influence on the photoinitiation activity. A possible interpretation is suggested.
- Benzophenone sensitizer,
- photopolymerization,
- Mechanism
