Polythiophene — O3 surface reactions studied by XPS

Novel Hybrid Materials Consisting of Regioregular Poly(3‐octylthiophene)s Covalently Attached to Single‐Wall Carbon Nanotubes

“…[22,23] In the spectrum of the rrP3OT film, the C1s core level is measured at 285.1 eV, with an FWHM of 1.5 eV (Figure 7c), and the S2p level is at 164.1 eV (not shown), in agreement with previous observations for similar films. [24] If the C1s XP spectrum is fitted with two components (285 and 286.7 eV) with an energy separation of 1.7 eV and an area ratio of 6:1, whereby the low-binding-energy peak relates to a C=C À C environment and the high-bindingenergy peak relates to a C=CÀS environment, [25] there exists a residual signal which requires the addition of a third component at 285.2 eV. Accordingly, the peak at 285.2 eV is attributed to an extra carbon concentration, which is present on the surface of the film due to its exposure to the atmosphere.…”

Oxidation behavior of P3HT layers on bare and TiO2-covered ZnO ripple structures evaluated by photoelectron spectroscopy

“…The chamber was composed of a quartz window which was used to allow light exposure to the sample from an external source. 10,11,26 No additional state appeared at binding energies above 168.0 eV, indicating that the conjugated ring structure of P3HT was mostly maintained during humid air exposure for 18 h. 10,13,26,27 Fig. Fig.…”

Highly selective CO2 capture by S-doped microporous carbon materials

“…However, in the a-SG5 to a- Figure S8) [42,43]. In the a-SG samples an additional peak appears at 168 eV due to oxidized S. Figure 4 shows the N 2 adsorption-desorption isotherms of the SG material before and after chemical activation.…”
