Abstract: | The kinetics of a two-stage laser-induced reaction between electronically excited molecules of two sorts (an organic luminophore
and oxygen) in a regular porous nanostructure whose cells are filled with linear macromolecules is studied. A mathematical
model of the process is proposed that takes into account an inhomogeneous distribution of polymer chain links in a nanopore,
with this distribution determining the radial profile of reagents. One version of the theory considers a radial diffusion
flux of activated oxygen molecules, while the other version considers a thermodiffusion flux of unexcited molecules. The numerical
results of the model are compared to the data of molecular dynamic calculations and experiment. |
