Source of material

Dichloromethane was freshly distilled from CaH2 under a dry nitrogen atmosphere. Dipyrromethane [1], 2-methoxy-1-naphthylboronic acid [2] and n-hexadecyloxyl benzaldehyde [3] were prepared according to the published procedures. All other reagents and solvents were used as received. The complex ZnDNP was prepared according to the published procedures [4]. Suitable crystals of the title compound were obtained by slow diffusion of hexane into a solution of 1 in CHCl3/pyridine (100:1, v/v). The target compound ZnDNP was characterized by mass spectrometry, NMR spectroscopy, and electronic absorption spectroscopies in addition to elemental analysis. Crystal of ZnDNP was grown by liquid diffusion of hexane into a solution of ZnDNP in CHCl3/pyridine (100:1 v/v). 1H-NMR (CDCl3, 400 MHz, 293 K): δ 8.865 (m, 2H), 8.809 (m, 2H), 8.675 (m, 4H), 8.235 (d, 2H, J = 4.4 Hz), 8.205 (d, 2H, J = 4.4 Hz), 8.163 (d, 2H, J = 4.8 Hz), 8.043 (d, 2H, J = 4.8 Hz), 7.995 (M, 2H), 7.685 (m, 3H), 7.616 (d, 2H, J = 4.8 Hz), 7.306 (m, 2H), 7.107 (m, 2H), 6.972 (m, 2H), 6.785 (d, 2H, J = 8.0 Hz); 13C-NMR (CDCl3, 100 MHz, 293 K): δ 154.48, 150.84, 138.07, 135.64, 132.72, 131.20, 131.10, 130.41, 128.39, 127.64, 126.44, 123.03, 122.00, 117.55, 113.41, 110.93; UV-vis (CHCl3): λmax (log ϵ) 423 (5.62), 547 (4.43), 580 (3.80).

Experimental details

The hydroxy H atoms were located in difference Fourier maps and their positions were refined with O—H bond-length restraints of 0.84(1) Å and with Uiso(H) = 1.2Ueq(O). The remaining H atoms were positioned in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.93 (aryl), and with Uiso(H) = 1.5Ueq(C).

Discussion

In the title structure the Zn center is five-coordinated by four pyrrole nitrogen atoms of porphyrin and one pyridine nitrogen atom, forming slightly distorted rectangular pyramid coordination geometry. The bond distance of Zn—N(pyridine) (2.145(3) Å) is longer than the mean Zn–N(porphyrin) bond distance (2.073(3) Å), both are similar to the corresponding reported values for other pyridine–Zn–porphyrin systems [5]. Due to the axial coordination of pyridine ligand, the Zn center deviates from the N4 mean plane (0.34 Å) and points to the axial pyridine ligand. As expected, the two naphthyl rings are almost perpendicular to the plane defined by the four nitrogen atoms of the porphyrin with a dihedral angle of 89.61° and 79.54°. This indicates a highly restricted rotational freedom of the 2-hydroxynaphthyl group due to the large steric hindrance effects. Notably, another pyridine molecule also binds to the porphyrin host via hydrogen bonding of N(pyridine)–HO(2-hydroxynaphthyl). Furthermore, a one-dimensional (1D) supramolecular double-chain structure can be observed in the crystal of the title compound ZnDNP, the linkages include: 1) hydrogen bondings of O(2-hydroxynaphthyl)⋯HO(4-hydroxyphenyl) and N(pyridine)⋯HO(2-hydroxylnaphthyl), with distances of 1.970(6) and 2.080(5) Å respectively. Here, the hydroxyl of naphthyl are both, hydrogen bonding donor and acceptor. 2) π-π stacking interactions of pyridine-porphyrin and pyridine-pyridine, with inter-ring distances of 3.249 and 3.359 Å, respectively. The above observations imply that the porphyrin ZnDNP can be a receptor with multiple binding sites and multiform intermolecular interactions [6].
