Synthesis and spectral properties of iron(III) tetra- tert -butylphthalocyanine complexes

Unraveling the Electronic Structure and Dynamics of the Atomically Dispersed Iron Sites in Electrochemical CO2 Reduction

“…In the class of iron phthalocyanine materials, HS ferric phthalocyanine was synthesized and studied by Mossbauer spectroscopy by Burtsev et al, with reported IS and QS values of 0.3 and 0.7 mm s −1 , respectively, at room temperature. 45 These values match well with those observed in the present work, and combined with the other results, support the successful synthesis of FePc-CNT with atomically dispersed HS O 2 -Fe(III)N 4 species in ex situ conditions.…”

Electrochemical and spectroelectrochemical studies of tert-butyl-substituted aluminum phthalocyanine

“…In this work, we conducted voltammetric and spectroelectrochemical studies of tert-butyl-substituted Al phthalocyanine ( tBu PcAlCl) in a non-coordinating solvent o-DCB. The bulky tert-butyl groups were introduced at the peripheral positions to increase solubility and lower aggregation of the complex in organic solvents [27,28]. This is the first detailed electrochemical study of an aluminum phthalocyanine in a non-coordinating and the first detailed spectroelectrochemical study that particularly revealed influence of aggregation in the neutral and oxidized forms on electrochemical and UV-Vis spectral properties.…”

Fenton reaction-driven pro-oxidant synergy of ascorbic acid and iron oxide nanoparticles in MIL-88B(Fe)

“…57 Fe Mo ¨ssbauer absorption spectra were measured using a transmission geometry with a moving source and triangular velocity reference signal on an express Mo ¨ssbauer spectrometer MS1104EM (CJSC Kordon, Rostov-on-Don, Russia) at temperatures of 77.7 AE 0.3 K and 296 AE 3 K. The g-radiation source consisted of 57 Co embedded in a metallic rhodium matrix with an activity of 25 mCi (Cyclotron Co., Ltd, Obninsk, Russia) and was kept at room temperature. An a-Fe foil served as the reference absorber for velocity calibration.…”
