“…4(a). These peaks are deconvoluted to peaks representing C sp 2 (284.5 eV), C sp 3 (285.0 eV), and C-Cl (285.9 eV), and π-π satellite peaks (291.0 eV), with an sp 2 /sp 3 ratio of 3.5 according to Gaussian fitting, 30,41,42 and the atomic compositions are C (89.2%), O (0.5%), and Cl (10.3%), as shown in Table S2. † When this film is pyrolyzed at 900 °C under N 2 gas, the two apparent peaks at 285 and 291 eV are no longer clearly separated, as shown in Fig.…”
