Crystalline complexes, coordination polymers and aggregation modes of tetra(4-pyridyl)porphyrin

62 Porphyrin-Based Tectons in Molecular Tectonics

“…This type of architecture was reported some 20 years ago by Fleischer and Schachter in their pioneering work 42 on ZnPy 1 Po. The same type of coordination network was also reported later 43 for the zinc complex of meso-tetra-pyridylporphyrin ZnPy 4 Po. Hosseini and coworkers also reported the formation of geometrically analogous networks for both positional isomers of the zinc complex of meso-bis-pyridylporphyrins, cis-ZnPy 2 Po 44 and trans-ZnPy 2 Po bearing 4-trifluoromethylphenyl groups at the 10,20-meso positions.…”

Facile synthesis and characterizations of copper–zinc-10,15,20-tetra(4-pyridyl) porphyrin (Cu–ZnTPyP) coordination polymer with hexagonal micro-lump and micro-prism morphologies

“…As shown in Fig.2, the Cu-ZnTPyP hexagonal micro-lumps and micro-prisms exhibit similar XRD patterns (curve a), which are different from the previously reported CuTPyP micro-spindles(curve d) [16]. By comparing with previous reports, we find that the XRD patterns for the two [19]. In these microstructures, the zinc atom at the center of ZnTPyP should be six-coordinated to four pyrrole nitrogens of the porphyrin core and two pyridyl N-atoms of the other porphyrin molecules, which approach from both sides of the molecular framework [20].…”

1D and 2D solid-state metallosupramolecular arrays of freebase 5,10,15,20-tetra(4-pyridyl)porphyrin, peripherally linked by zinc and manganese ions

“…In particular, the construction of infinite metallosupramolecular multiporphyrin arrays using the exocyclic coordination ability of the peripheral pyridyl groups of the readily accessible 5,10,15,20-tetra(4-pyridyl)porphyrin (TPyP) to external metal ions originated from the pioneering work of Robson and coworkers [5,6]. Up to now many coordination polymers bearing the TPyP moiety as a ligand are known [7][8][9][10][11][12][13][14][15][16][17]. Recently the first discrete metallosupramolecular open molecular box containing TPyP as walls was reported [18].…”
