Heterocycle-appended lanthanum(III) sandwich-type (porphyrinato)(phthalocyaninates)

Functionalized heterocycle-appended porphyrins: catalysis matters

“…These peculiarities of tetrakis(4-butoxyphenyl)porphyrin have already been successfully used for the elaboration of a new class of sandwich-type complexes formed from phthalocyanine and heterocycle-appended porphyrin ligands bearing terminal reactive halogen atoms. 36 Accordingly, the extension of the series of functionalized porphyrins fused with different heterocycles is assumed to be of interest for the further design of hybrid materials based not only on porphyrin derivatives, but also on the sophisticated tetrapyrrolic polyaromatic systems.…”

“…The solvents were puried according to conventional methods. 45 The starting 2-amino-3-nitro-tetrakis(4-butoxyphenyl)porphyrinato nickel(II) 1, 28,36,46 2-amino-3-nitro-tetramesitylporphyrinato nickel(II), 35 and 4-diethoxyphosphorylbenzaldehyde 3g 44,47 were prepared following the conventional procedures. 2,3-Diaminotetramesitylporphyrinato nickel(II) 7 was generated following the published procedure.…”

“…34,38 Furthermore, the latter methodology was implemented for the elaboration of a novel class of heteroleptic sandwich-type lanthanide (porphyrinato)(phthalocyaninates) 39,40 based on heterocycle-appended porphyrin ligands. 36 In this case, the inuence of the annulated N-cycle on the electronic structure of the entire molecule was revealed by UV-vis spectroscopy.…”

“…17,[23][24][25][26][27][28][29][30][31][32][33] Recently, we developed synthetic strategies towards imidazole-and pyrazine-annulated porphyrins starting from tetrapyrrole dioxo-or diamino-derivatives and aromatic aldehydes. 28,[34][35][36][37][38] The sterically hindered tetrapyrrole was used as a synthetic platform for the development of bifunctionalized linear and angular annulated polyaromatic compounds, water soluble derivatives for biomimetic applications and macrocycles with terminal anchoring groups. 34,38 Furthermore, the latter methodology was implemented for the elaboration of a novel class of heteroleptic sandwich-type lanthanide (porphyrinato)(phthalocyaninates) 39,40 based on heterocycle-appended porphyrin ligands.…”

Lanthanide–tetrapyrrole complexes: synthesis, redox chemistry, photophysical properties, and photonic applications

“…189 With more comprehensive studies on lanthanide-porphyrin multiple-decker complexes progressing, it is also promising to modify the pyrrole units. Birin et al 190 demonstrated a new family of multiple-decker complexes bearing heterocycle-appended porphyrins.…”
