“…The template synthesis based on phthalonitriles is the simplest method for obtaining monophthalocyaninates of lanthanides [36]. Unsubstituted phthalocyaninates of Sm(III), Gd(III), Yb(III), Lu(III), as well as tetrachloro-, tetrabromo-, tetranitro-, and tetra-crown-substituted complexes of lutetium have been synthesized using this method [37].…”

This review is devoted to different synthetic approaches for obtaining lanthanide complexes with porphyrins and phthalocyanines, studying their structure and emission features. Lanthanide-tetrapyrroles can be core-coordinated or/and coordinated by additional binding sites in polytopic derivatives. It is noteworthy that the polytopic tetrapyrroles allow obtaining polyheteronuclear compounds, which is quite interesting in terms of their particular 4f-sensitization mechanism. A general structural difference between core-coordinated lanthanide-porphyrins and lanthanide-phthalocyanines is the ability of the latter to easily form poly-decker compounds, which leads to interesting changes in photochemical processes including 4f-sensitization. The review also shows the main directions for the solution of the stability issue as well as different approaches for increasing the 4f-luminescence effectiveness.

“…Thus, it can lead to higher singlet oxygen production and a reduction in other competitive relaxation pathways, such as fluorescent emission (Svec et al 2015). Despite promising properties and unique structural features, little attention has been paid to pyrazinoporphyrazine complexes of rare earth elements (Botnar, et al 2022). Therefore, it is essential to develop an efficient synthesis and characterization of novel pyrazinoporphyrazine complexes containing rare earth metal ions.…”

A new tetrakis-(2-methylpyrazino)porphyrazinato gadolinium(III) acetate complex was synthesized. Elemental analysis, Fourier-Transform Infrared, Ultraviolet-visible, and fluorescence spectroscopy techniques clarified its structure. It can dissolve very well without aggregation in both Dimethyl sulfoxide and N, N-Dimethylformamide, which have high dielectric constant and high dipole moment from polar aprotic solvent type. Its aggregation property was also investigated in dimethyl sulfoxide at different concentrations, and it was determined to contain monomeric species. In addition, its fluorescence properties were investigated in Dimethyl sulfoxide and the effect of gadolinium(III) acetate metal ion as a heavy rare earth element was determined. According to the findings in this study, it may be used as an electronic and optical material and in various technological applications such as photocatalytic applications. In addition, these findings may be useful for systems that include changes in pyrazinoporphyrazine-like forms.
