Time-resolved laser-spectroscopy investigation has been performed for the first time on the excited state interaction of different ketocoumarins with onium salts in methanol. Ketocoumarins'triplet state quenching by monomers lead to evaluate the quan

Interaction between Rose Bengal (RB) and an iron arene complex [Irg(+)] was studied by steady state and laser flash photolysis experiments. The contribution of static fluorescence quenching is evidenced by time resolved fluorescence experiments and c

The photophysics and photochemistry of thiopyrylium salts have been investigated by UV–VIS absorption spectroscopy and nanosecond laser absorption spectroscopy. The effect of substituents of the heterocycle on the photophysical properties was analy

The choice of photoinitiators is partly governed by the requirement of a high curing speed. Many reactive monomers and efficient photoinitiators have been synthesized and are commercially available. However, improved photoinitiator systems, exhibitin

Excited state processes of a large variety of polymerization photoinitiators (based on morpholino, hydroxyalkyl, amino ketones) in the presence of photosensitizers belonging to the thioxanthone series have been investigated through time-resolved lase

The design of an efficient photosenzitizer/photoinitiator combination is partly governed by a better understanding of the excited state processes involved. In the present paper, the photochemistry of a thiopyrylium salt (TP) as photosensitizer and of

The excited-state interactions between photoinitiators and thioranthones used as photosensitizers were investigated. The thioranthones are shown to interact with α-morpholino-substituted acetophenone photoinitiators bearing various substituents on t

Peroxyl radicals are usually assumed as key intermediates in oxidation or autoxidation processes rendering important a better understanding of their associated reactivity. Kinetic ESR is proposed here as an efficient technique for the determination o

Nowadays, radiation curing is a well-established technology that has developed and grown rapidly on an industrial scale. The most prominent applications initially related to the UV curing of coatings, while reprography (printing plates, integrated ci
