Vibrational spectroscopy of phthalocyanine and naphthalocyanine in sandwich-type (na)phthalocyaninato and porphyrinato rare earth complexes

Visible light-driven photophysics and photochemistry of water-soluble metalloporphyrins

“…Lanthanide(III) ions offer good opportunities for fine tuning of the out-of-plane distance, utilizing the monotonous decrease of their radii from 116 pm to 98 pm (at coordination number 8) upon increasing atomic numbers [12]. Additionally, they prone to form bis-or oligoporphyrins [31,32,33], the photoinduced properties of which strongly depend on the π-π interaction between the macrocycles. Notably, porphyrins are able to efficiently sensitize the near-infrared luminescence of lanthanide ions, which can be widely applied from telecommunication to biomedical optical imaging [34,35].…”

Distribution of the unpaired electron in neutral bis(phthalocyaninato) yttrium double-deckers: An experimental and theoretical combinative investigation

“…Figure 3 displays the IR spectra of 1-5. As can be found, in addition to the absorption bands contributed from the Pc macrocycle including the wagging and torsion vibrations of the C-H groups, isoindole ring stretching vibrations, and the C=N aza group stretching vibrations [23], intense absorption bands due to the C−H stretching vibrations of the −CH 2 − and −CH 3 groups of the side chains are observed at ca. 2750−3000 cm -1 in the IR spectra of 2-5, which disappear in the unsubstituted double-decker complex 1.…”

Reactivity of Rare Earth Metal Porphyrins/Phthalocyanines in Acid Media

“…X-Rray crystallography data for triple-decker complexes are not numerous [19,20] whereas double-decker complexes including mixed (phthalocyaninato)(porphyrinato) complexes have been studied intensively. [15][16][17][20][21][22][23][24][25][26][27][28] The results of molecular structure studying by means of density functional theory calculations or by systemizing of vibrational characteristics of bis-and tris-[(na)phthalocyaninato] and mixed (porphyrinato)[(na)phthalocyaninato] complexes [26,29] were published. Rare earth metal doubledecker and triple-decker complexes with different phthalocyanine and porphyrin macrocycles in the same molecule are constructed.…”
