Synthesis, characterization and thermal degradation kinetics of ferrocene-containing aramids

Liquid‐crystalline azobenzene‐containing ferrocene‐based polymers: study on synthesis and properties of main‐chain ferrocene‐based polyesters with azobenzene in the side chain

“…All the polymers exhibited the main characteristic peaks of ferrocene‐based polymers such as the C–H stretching vibration of the ferrocene unit, the aliphatic C–H stretching vibrations, stretching vibration of the carbonyl group, C–O–C and C–O stretching vibrations, aromatic C–H bending vibration, and Fe–Cp stretching vibration. The FT‐IR spectra showed the characteristic peaks of ferrocene‐based polyesters and the spectra coincide with the literature . In particular, the cyano azobenzene‐containing main‐chain ferrocene‐based polyester PPFD‐CN possessed a unique peak at 2220 cm –1 , which is characteristic to the stretching vibration of –C≡N group.…”

Study on the electrochemical, thermal, and liquid crystalline properties of poly(diethyleneglycol 1,1′-ferrocene dicarboxylate)

“…Furthermore, the aromatic C-H bending vibration and Fe-Cp stretching vibration appear at 802 and 492 cm À1 , respectively. The FTIR spectrum shows the characteristic peaks of a ferrocene-based polyester and the spectrum coincides with the literature [2,[37][38][39][40][41][42][43].…”

“…The curves of TGA and DTA are shown in Figure 5. The initial temperature at which cumulative weight change has a magnitude that can be detected by the thermobalance known as T in [41], the temperature of 5% weight loss (T 5 ), the temperature of 10% weight loss (T 10 ), the temperature at the end of the curve (T f ), the temperature of maximum weight loss (T s ), and the char yield are mentioned in Table 4.…”

Synthesis, physicochemical studies and potential applications of high-molecular-weight ferrocene-based poly(azomethine)ester and its soluble terpolymers

“…The thermograms showed that the poly(azomethine) ester and its terpolymers comprise of amorphous nature. The presence of bulky aromatic, cyclopentadienyl rings and polar C]N group prevent close packing and alignment of the chains resulting in amorphous polymers [22].…”
