Direct and sensitized photolysis of phosphine oxide polymerization photoinitiators in the presence and absence of a model acrylate monomer: A time resolved EPR, cure monitor, and photoDSC study
Article Abstract:
The effect of triplet sensitizers on the photoinitiated polymerization (cure) of a model acrylate monomer, isobornyl acrylate (IBOA) is investigated with time-resolved electron paramagnetic resonance (Tr EPR) spectroscopy and cure monitoring and photodifferential scanning calorimetry (photoDSC). It is suggested that photosensitization may provide a means of manipulating and controlling the parameters of photocuring of acrylates.

Study of charge-transfer complexes of [60]- and [70]fullerenes with a series of phosphine oxides
Article Abstract:
Equilibria for the formation of molecular electron donor-acceptor (EDA) complexes of a series of phosphine oxides with [60]- and [70] fullerenes are investigated in CCl4 medium. The kinetic study of a slow chemical reaction of the two fullerenes in their ground state with one phosphine oxide, which is, the labile BEHP-fullerene complexes decay by a path first order with respect to the complexes is reported.

Oximetry of oxygen supersaturated solutions using nitroxides as EPR probe
Article Abstract:
The broadening of the three-hyperfine EPR nitroxide lines in oxygen-supersaturated solutions was examined. The solutions were supersaturated with oxygen either by thermal decomposition of 1,4-peroxy-1,4-dimethylnaphthalene or by pressurizing molecular oxygen above the sample solution, to describe the requirement for spectral simulation in this region of line broadening.
