Scanning tunneling microscopy (STM) and spectroscopy (STS) are used in this work to investigate the charge-transfer effect at the molecule-substrate interface of substituted metal phthalocyanines. STS results revealed that the apparent energy gaps for both fluorinated phthalocyanines and unsubstituted phthalocyanines are essentially the same, which agree(More)
In the title compound, [Cu(C(76)H(92)N(4)O(4))], the central Cu(II) ion is situated on an inversion centre. The porphyrinate core exhibits a nearly planar conformation [maximum deviation = 0.027 (3) Å], with Cu-N distances of 1.997 (2) and 2.001 (2) Å. The benzene rings of the 4-octyloxyphenyl groups are rotated at angles of 84.02 (8) and 77.02 (6)° with(More)
In the title compound, [Ni(C(72)H(84)N(4)O(4))], the four-coordinate Ni(II) ion in the middle of the planar 24-membered porphyrin ring is located on a crystallograpic inversion center, with Ni-N distances of 1.946 (2)-1.951 (2) Å. The 4-heptyl-oxyphenyl groups are twisted with respect to the porphyrin mean plane, the dihedral angles being 88.5 (3) and 79.1(More)
The mol-ecule of the title compound, [Ni(C(68)H(76)N(4)O(4))], is located on a crystallographic inversion center. The Ni-N distances within the square-shaped coordination environment are 1.951 (2) and 1.954 (2) Å. Three terminal C atoms in one of the hexyl groups are disordered over two sets of sites, with site-occupancy factors of 0.615 (13) and 0.385 (13).
The title compound, [Ag(C(72)H(84)N(4)O(4))], crystallizes with the Ag(II) cation on a centre of symmetry. The macrocyclic 24-membered ring core is planar with a mean deviation of 0.0311 (15) Å and the four-coordinate Ag(II) cation fits into its center, at 2.0814 (19) and 2.0872 (19) Å, from the surrounding pyrrole-N atoms, in agreement with what is found(More)
