Construction of redox- and photo-functional molecular systems on electrode surface for application to molecular devices

Porous Porphyrin Nanoarchitectures on Surfaces

“…[72][73][74][75] However, it has only recently been utilized in the fabrication of thin films of MOFs or crystalline coordination polymers. [18,[76][77][78][79][80][81] Shekhah et al first reported a step-by-step route of the synthesis of crystalline MOFs that was driven by the desire to understand the MOF formation process in a rational way rather than to attempt to fabricate MOF thin films.…”

A Back‐to‐Back Ligand with Dipyrazolylpyridine and Dipicolylamine Metal‐Binding Domains

“…[43] The asymmetric unit contains one complex tetracation, four PF 6 -anions, eight fully or partially occupied nitromethane solvent sites whose occupancies sum to 6.8, and a partial diethyl ether molecule that was refined with occupancy 0.3. Two of the four PF 6 -anions are disordered, and were modelled with the refined restraints P-F 1.60(2) Å, and cis-F···F 2.26(2) Å. The solvent content of the lattice is as follows: two wholly occupied nitromethane molecules; three crystallographically ordered nitromethane molecules with a reduced occupancy of occupancy 0.7; two disordered nitromethane sites, with total occupancies of 0.6 and 0.7; and, a 0.4-occupied nitromethane and a 0.3-occupied diethyl ether molecule occupying the same region of the asymmetric unit.…”

“…In [MCl(L)]PF 6 , however, the NCH 2 Py protons within the dpa fragment are observed as a pair of doublets, reflecting the diastereotopic nature of these groups when the conformation of the dpa fragment is locked by metal coordination. [29,30] 6 ] 4 (M = Pd, 1; M = Pt, 2; Scheme 1). Their ES mass spectra were identical to those of the corresponding [MCl(L)]PF 6 precursors, however, implying that the coordinated iron is lost under the conditions of the ES experiment.…”

“…[8] Derivatization at the 4Ј-position of the terpy scaffold, directly opposite a coordinated metal ion, is especially facile, which has allowed [M(terpy) 2 ] 2+ centres to be incorporated into all the types of structures mentioned above. [1][2][3]6,7] A related tridentate heterocyclic ligand for metal ions is 2,6-bis(pyrazol-1-yl)pyridine (1-bpp), which can also be derivatized at its periphery with a variety of substituents. [9] Although they are less well studied than the terpy system, two classes of 1-bpp complex are receiving particular attention.…”

“…Ditopic "back-to-back" ligands [1] are of continuing interest for the synthesis of metal-containing polymers, [2][3][4] dendrimers, [2,5] molecular wires [6] or other supramolecular structures. [7] The most versatile ligands for these applications are 2,2Ј:6Ј,2ЈЈ-terpyridine (terpy) derivatives, which can be readily prepared with a variety of substituents at the central or distal pyridine rings.…”
