A novel 1D independent metal–organic nanotube based on cyclotriveratrylene ligand

Abstract

A novel nanotubular metal-organic frameworkwas prepared by assembly of the rigid, trigonal pyramidal ligand tri-(4-carboxy-phenyl)trimethoxycyclobenzylene (H 3 L) and Cu(NO 3 ) 2 $3H 2 O via solvothermal reaction. The Cu(II) ions in the crystal serve as square and linear molecular building blocks, thus forming a framework with ternary topology. One single open-ended nanotube contains two identical orthogonally interpenetrated twonodal nets. This framework exhibits permanent microporosity and relatively high surface area.

Copper coordination polymers from cavitand ligands: hierarchical spaces from cage and capsule motifs, and other topologies

“…The coordination polymers reported here and elsewhere 9–15 demonstrate that tris-ligand-functionalised CTV-type molecular hosts are excellent tectons for the self-assembly of metal–organic frameworks. The ability to predict the framework topologies that are produced remains elusive however, and both common and unusual topologies may result.…”

Lanthanide coordination polymers with pyridyl-N-oxide or carboxylate functionalised host ligands

“…The self-assembly of derivatised CTVs with metal cations is well established, and coordination polymers, [35][36][37] discrete metallo-cages, [38][39][40][41][42] and mechanically interlocked architectures [43][44][45] are known. However, the chemistry of mixed ligand systems is generally limited to the solution-phase, and we have recently demonstrated how the formation and manipulation of homo-and heteroleptic [Pd 6 L 8 ] 12+ octahedral cages can be controlled with high fidelity.…”

Tuning the coordination chemistry of cyclotriveratrylene ligand pairs through alkyl chain aggregation

“…Tripodal derivatives such as those shown in Scheme 1 are chiral. The self-assembly of derivatised CTVs with metal cations is well established, and coordination polymers, [35][36][37] discrete metallocages, [38][39][40][41][42] and mechanically interlocked architectures [43][44][45] are known.
