Ring-fused porphyrins: extension of π-conjugation significantly affects the aromaticity and optical properties of the porphyrin π-systems and the Lewis acidity of the central metal ions.
Here, we report the effects of ring fusion, which causes expansion of the π-conjugation circuits of the porphyrin derivatives to the fused meso-aryl groups, on the aromaticity and the magnetic properties of porphyrin derivatives. These studies revealed the facts that the ring fusion with five-membered rings causes not only the remarkable red shifts of the absorption bands and narrowed HOMO-LUMO...
متن کاملSolvent dependent supramolecular self-assembly and surface reversal of a modified porphyrin.
In this paper, a novel core-modified porphyrin with meso-aryl substituents and phenanthrene-fused pyrrole rings (N2S2-OR) is synthesized. Scanning tunneling microscopy (STM) has been used to probe its self-assembly behavior on a highly-oriented pyrolytic graphite (HOPG) surface. Our STM results have shown that there is an obvious solvent-dependent self-assembly for the surface-confined target m...
متن کاملFused pyrene-diporphyrins: shifting near-infrared absorption to 1.5 microm and beyond.
Porphyrins have been explored for a number of potential optoelectronic applications that require strong absorption in the near-infrared (NIR) spectral region; these applications include organic electronics, nonlinear optics, and telecommunication technologies. Porphyrins have also been investigated as active materials in photovoltaic cells because of their high efficiency of charge separation a...

متن کامل(5,15-Dianthracen-9-yl-10,20-dihexylporphyrinato)nickel(II): a planar nickel(II) porphyrin
The title compound, [Ni(C(60)H(52)N(4))], is an example of a meso tetra-substituted nickel(II) porphyrin with both meso aryl and alkyl residues. The mol-ecule exhibits a planar macrocycle with an average deviation of the 24 macrocycle atoms from their least-squares plane (Δ24) of 0.01 Å and an average Ni-N bond length of 1.960 (2) Å. The Ni(II) atom lies on a center of inversion. The structure ...
