Excimer laser ablation of pentafluorophenylazide was investigated in an
inert matrix film at 8-10 K. A large amount of pentafluorophenylnitrene
was ejected explosively as fragments from the matrix by the ablation.
The photolysis of the azide was followed by UV, IR absorption spectroscopy,
and optical emission spectroscopy. It was found that the plume of the matrix
film was useful for the surface chemical modification of polymers.
Surface analysis of the materials by X-ray photoelectron spectroscopy indicated
that the nitrene was chemically immobilized on the surface.
