“…Phthalocyanines, as a result of their structural features and the possibility of introducing almost any functional moieties to their periphery, have found wide application in areas of societal and industrial importance such as catalysis, optics, medicine, light industry, etc. (Botnar et al, 2020(Botnar et al, , 2021. Substituted phthalocyanines, which attract the most attention, however, are obtained from phthalonitriles with various fragments in the 3 and 4 positions.…”

The syntheses and crystal structures are reported of 4-phenoxy-substituted phthalonitriles with methoxy groups in the ortho- and meta-positions of the terminal benzene rings, respectively, namely, 4-(2-methoxyphenoxy)phthalonitrile and 4-(3-methoxyphenoxy)phthalonitrile, both C15H10N2O2. The https://journals.iucr.org/e/issues/2023/03/00/molecular structure was determined using the single-crystal X-ray diffraction method. It is shown that short contacts play a more decisive role in the molecular packing compared to van der Waals interactions.

The review presents a generalization of research on the chemistry of solutions and materials based on linear and cyclic polypyrrole compounds carried out at the Department of Inorganic Chemistry of the Ivanovo State University of Chemistry and Technology. The review focuses on key areas related to synthetic approaches to the preparation of boron complexes with pyrrole derivatives, as well as complexes of a wide range of metals of the periodic system with substituted derivatives of the phthalocyanine ligand. Spectroscopic, luminescent, acid-base properties of synthesized compounds and their practical application in sensor systems are considered separately. In addition, the possibilities of obtaining hybrid and functional materials, including derivatives of borondipyrrins and tetrapyrrole macroheterocyclic compounds, which have increased catalytic and biological activity in liquid-phase processes are shown.

Mitigating Cobalt Phthalocyanine Aggregation in Electrocatalyst Films through Codeposition with an Axially Coordinating Polymer

Cobalt phthalocyanine (CoPc) is a promising molecular catalyst for aqueous electroreduction of CO2, but its catalytic activity is limited by aggregation at high loadings. Codeposition of CoPc onto electrode surfaces with the coordinating polymer poly(4‐vinylpyridine) (P4VP) mitigates aggregation in addition to providing other catalytic enhancements. Transmission and diffuse reflectance UV–vis measurements demonstrate that a combination of axial coordination and π‐stacking effects from pyridyl moieties in P4VP serve to disperse cobalt phthalocyanine in deposition solutions and help prevent reaggregation in deposited films. Polymers lacking axial coordination, such as Nafion, are significantly less effective at cobalt phthalocyanine dispersion in both the deposition solution and in the deposited films. SEM images corroborate these findings through particle counts and morphological analysis. Electrochemical measurements show that CoPc codeposited with P4VPonto carbon electrode surfaces reduces CO2 with higher activity and selectivity compared to the catalyst codeposited with Nafion.
