The first 5,10,15,20-tetra-(4-(triazol-1-yl)phenyl) porphyridine complex, [Zn${}_{\mathrm{\text{2}}}$Cl${}_{\mathrm{\text{4}}}$(5,10,15,20-tetra-(4-(triazol-1-yl)phenyl)porphyridine)]${}_{n}n$Cl•$n$H${}_{\mathrm{\text{3}}}$O•7$n$H${}_{\mathrm{\text{2}}}$O (1) has been synthesized via solvothermal reactions and characterized by single-crystal X-ray diffraction. Complex 1 is characteristic of a one-dimensional (1-D) structure, consisting of neutral [Zn${}_{\mathrm{\text{2}}}$Cl${}_{\mathrm{\text{4}}}$(5,10,15,20-tetra-(4-(triazol-1-yl)phenyl) porphyridine)]${}_n$ chains, isolated chloride ions and lattice water molecules. The zinc ion is in a four-coordinated tetrahedral geometry, and the porphyrin macrocycle is saddle-distorted. Photoluminescence measurement with solid-state samples discovers that it exhibits an emission in the green region of the light spectrum. Time-dependent density functional theory (TDDFT) calculation discovers that this emission can be attributed to the $\pi$–$\pi$* charge transfer. The cyclic voltammetry (CV) measurement reveals that it possesses an oxidation peak at 0.37 V.

A novel neodymium porphyrin [Nd(TPPS)]${}_n$•$n$H${}_{\mathrm{\text{3}}}$O (1) [H${}_{\mathrm{\text{6}}}$TPPS $=$ tetra(4-sulfonatophenyl)porphyrin] has been prepared through a solvothermal reaction and characterized by the X-ray single-crystal diffraction technique. Complex 1is crystallized in the $P$4/mcc space group of the tetragonal system. Complex 1 features a three-dimensional (3D) open framework with the pore size of the channels being of 6.9 $\AA$ × 8.2 $\AA$. A wide optical band gap of 4.98 eV is revealed by the solid-state UV/vis diffuse reflectance spectrum. The variable-temperature magnetic susceptibility obeys the Curie-Weiss law (${\chi }_m=c$/($T𝜃))$ with $C=$ 0.67 K and a negative Weiss constant $𝜃=$ -0.37 K as found by the magnetic measurements, suggesting the existence of an antiferromagnetic behavior. The N${}_{\mathrm{\text{2}}}$ adsorption and desorption curves show good reversibility and verify that the 3-D framework is flexible and can be compressed with the increasing pressure.
