Pulsed infrared laser-induced ablation of poly(1,4-phenylene ether-sulfone) (PES) results in the extrusion of SO2, CO and hydrocarbon molecules and allows deposition of dark solid paramagnetic carbonaceous films that are poor in S and contain SO2, -SO- and C-S-C units. The films show pronounced conjugation of sp2-C atoms and their EPR spectra are sensitive function of the presence of molecular oxygen.
IČ laserově indukovaná ablace poly(1,4-fenylen ether sulfonu) vede k eliminaci SOě, CO a uhlovodíků a dovoluje deposici pevných paramagnetických filmů, které jsou chudé na síru a obsahují SO2, SO, CO a C-S-C skupiny.Filmy vykazují významnou konjugaci sp2 C atomů a jejich EPR spektra jsou citlivá na přítomnost kyslíku.
