| Abstract: | he
photochemical properties of eight novel watersoluble thioxanthone photoinitiators were studied
by UV absorption, fluorescence and ESR. The maximal UV absorption wavelength and
extinction coefficient, fluorescence quantum yield and the signal intensity of ESR were
determined. The relationship between the structure and the photochemical properties was also
discussed.\= |
