Control of supramolecular organizations by coordination bonding in tetrapyridylporphyrin thin films

Abstract

The edge-on and face-on orientations of tetrapyridylporphyrin are selectively obtained in a thin film by changing the central metal ion of the porphyrin ring.

Synthesis of a New Co Metal–Organic Framework Assembled from 5,10,15,20-Tetrakis((pyridin-4-yl) phenyl)porphyrin “Co-MTPhPyP” and Its Application to the Removal of Heavy Metal Ions

“…The infrared spectrum of Co-MTPhPyP ( Figure 3 ) confirmed the presence of the band assigned to pyridine around about 1592 cm −1 with satellite band at 1605 cm −1 for CoTPhPyP according to Tomita et al [ 21 ]. The intense band for the TPhPyP ligand (1416 cm −1 ) attributed to the superposition of pyridine vibrations in shifted to 1384 cm −1 upon coordination with cobalt and the bands at 998 cm −1 and 800 cm −1 for to the deformation of the porphyrin ring and the deformation of the pyrrole nucleus, respectively, remained unaffected.…”

“…In conclusion, considering the FTIR, XRD and XPS analysis, a possible 2D structure of Co-MTPhPyP is shown in Figure 7 , in accordance with the reported by Sengupta et al [ 24 ] with a Cu-MOF. Suggesting the form 2D network structure with a face-on arrangement in accordance with Tomita et al [ 21 ].…”

Construction of a two-dimensional metal–organic framework with perpendicular magnetic anisotropy composed of single-molecule magnets

“…S5, ESI†), which was collected by membrane filtration and used for PXRD, IR, and AC magnetic measurements (discussed later). The formation of Py–Pd 2+ bonds in 1Pd was supported by the characteristic shift of the CC stretching of Py 33 from 1592 cm −1 to 1608 cm −1 , which was further supported by frequency calculations for the free Py and [Pd(Py) 4 ] 2+ complex at B3LYP/Def2-SVP 34–36 level (Fig. S12, ESI†).…”

Two-dimensional metal–organic nanosheets composed of single-molecule magnets: structural modulation and enhanced magnetism utilizing the steric hindrance effect

“…S19, ESI †). 26,41 The film formed at the liquidliquid interface (1 Pd *-5 Pd *) should have a less ordered structure than that formed at the air-liquid interface (1 Pd -5 Pd ) because of the large structural roughness of the liquid-liquid interface.…”
