Thermal degradation of some ferrocene-containing poly(aryleneethynylene)s

Elucidating the thermal degradation of carbazole‐containing platinum–polyyne polymers

“…The detected ionic fragments most probably resulted from the splitting of hexadecyl CC lateral chains, which could be categorized into triplets with the general formulas C n H 2 n ‐1 , C n H 2 n , and C n H 2 n +1 , m / z = 41 (C 3 H 5 + ), 42 (C 3 H 6 + ), and 43 (C 3 H 7 + ); m / z = 55 (C 4 H 7 + ), 56 (C 4 H 8 + ), and 57 (C 4 H 9 + ); m / z = 69 (C 5 H 9 + ), 70 (C 5 H 10 + ), and 71 (C 5 H 11 + ); and m / z = 83 (C 6 H 11 + ), 84 (C 6 H 12 + ), and 85 (C 6 H 13 + ). Fragments with carbon atoms between 7 and 16 have a very low ionic current intensity, as described in a previous study . Figure shows the ionic current variations of some ionic fragments with increasing temperature.…”

“…We conducted the TG study (Figure and Figure S6 in the Supporting Information) by applying the TG–MS–FTIR coupling technique, which allowed for the attainment of concrete information on the initiation of thermal decomposition. The recorded MS spectra (Figure ) suggested that as anticipated previously, the thermal decomposition of both polymers started with the triethyl phosphine moieties, and this was followed by the splitting of the hexadecyl CC lateral chains (α scission in Scheme ). The temperature‐dependent variations of ionic currents ascribed to some specific fragment ions are shown in Figure .…”

“…We obtained information about the points of chain scissions to produce the volatile products of the polymers by applying the coupled TG–MS–FTIR technique. The equipment consisted of an STA 449F1 Jupiter thermogravimetric analysis device (Netzsch, Germany) coupled with an FTIR Vertex‐70 spectrophotometer (Bruker, Germany) and a QMS 403C Aёolos mass spectrometer (Netzsch, Germany) . Samples with a mass of 13.71 ± 0.04 mg were analyzed under a nitrogen atmosphere at a flow rate of 20 mL/min and a heating rate of 15 °C/min between 25 and 670 °C.…”

“…Accumulated knowledge obtained from the thermal analysis studies of various types of polymers suggests that structural changes can improve the thermostability of polymers without deteriorating their physical and mechanical properties. Combined thermogravimetry (TG)–mass spectrometry (MS)–Fourier transform infrared (FTIR) studies are useful for the estimation of the structure–thermostability–degradation mechanism relationship …”

Synthesis, physicochemical characterization, geometric structure and molecular docking of new biologically active ferrocene based Schiff base ligand with transition metal ions

“…Ferrocene is a highly redox‐active organometallic substance, which has been employed as magnetic, optical, and electrochemical materials. Also, chemical modification through organic synthesis enabled the synthesis of various ferrocene derivatives and ferrocene‐containing polymers The coordination chemistry of the complexes involving Schiff base ligands having O and N donor atoms and a number of transition metal ions has become area of much focus due to the versatility of Schiff base ligands on treating with transition metal ions produces mono as well as polynuclear complexes, which have been widely employed in material science and medicine. The Schiff base complexes may incorporate planar aromatic or flexible polydentate ligands .…”
