ESR dosimeters based on metallodiphthalocyanines: Correlation between ESR and spectrophotometric data

Synthesis and spectral parameters of symmetric and unsymmetrical sandwich-like double- and triple-decker lanthanide complexes containing 1-methyltetrabenzooctadehydrocorrin and phthalocyanine fragments

“…These compounds are capable of coordinating many elements of the Periodic Table, including lanthanides, to form coordination compounds with various structures, both single-decker and sandwich-like [4]. The latter may be used as sensors [5][6][7], materials for ionizing radiation detectors [8], dyes for passive synchronization of laser modes [9], and electrochromic materials [10]. Among numerous sandwich-like complexes, mixed-ligand coordination compounds containing tetrabenzoporphyrin and phthalocyanine fragments were studied most poorly [11,12], whereas coordination compounds based on tetrabenzocorrins were not reported at all.…”

Erbium complexes of “sandwich” type containing fragments of meso-tetraphenyltetrabenzoporphyrin and phthalocyanines of different structures synthesis and spectral properties

“…The latter are characterized by the overlapping of the π-orbitals of ligands depending on the size of the lanthanide ionic radius and on the geometric structure of the macrocycles. This effect opens an opportunity to apply sandwich compounds in various fi elds of science and technology [2][3][4][5][6][7][8]. Nowadays numerous synthetic procedures are known for the preparation of diphthalocyaninates both of symmetric and unsymmetrical structure [9][10][11][12].…”
