“…Moreover, the typical peaks of PPy at 1558 and 1478 cm −1 (the CC bond and the C–N bond) also appear in the PPy-0.5TcCoPc hybrid. 63,64 Meanwhile, the doping and polymerized states of PPy are represented by 1191, 1049, 925 and 794 cm −1 with a certain shift, respectively. 65,66 The doping of TcCoPc can be further evidenced from the Raman spectra (Fig.…”
