“…56,57 In our previous research on Pd(II)based coordination self-assemblies, the leaving ligand contributes to the modulation of the free energy landscape, resulting in changing the self-assembly pathway and the outcome. 58,59 We then investigated the kinetic effect of the leaving ligand on the Rh-based self-assembly. 2,6dichlorobenzoate (dcb -) was chosen as the leaving ligand (Fig.…”

Self-assembled coordination squares consisting of cis-protected dinuclear Rh(II) corner complexes and linear ditopic ligands were selectively produced in solution under kinetic control with the assistance of a weak monotopic carboxylate ligand (2,6-dichlorobenzoate: dcb–) as a leaving ligand. Preventing the cyclization step in the triangular formation by the leaving ligand enabled to produce the molecular square only. It was also found that dcb– can selectively convert the triangular complex into the square complex at room temperature, though heating at 373 K for 2 days is needed for the conversion without dcb– and that DMSO blocked the transformation process with dcb–. These results indicate that the energy landscape of the Rh(II)-based molecular self-assembly can be modulated properly by monotopic carboxylate ligand and solvent so that the self-assembly proceeds under kinetic control. Furthermore, one of the molecular squares assembled into a dimeric structure by the solvophobic effect, whose structure was characterized by NMR spectroscopy and single-crystal X-ray analysis.

Heteroleptic metal−organic capsules, which incorporate more than one type of ligand, can provide enclosed, anisotropic interior cavities for binding low-symmetry molecules of biological and industrial importance. However, the selective selfassembly of a single mixed-ligand architecture, as opposed to the numerous other possible self-assembly outcomes, remains a challenge. Here, we develop a design strategy for the subcomponent self-assembly of heteroleptic metal−organic architectures with anisotropic internal void spaces. Zn 6 Tet 3 Tri 2 triangular prismatic and Zn 8 Tet 2 Tet′ 4 tetragonal prismatic architectures were prepared through careful matching of the side lengths of the tritopic (Tri) or tetratopic (Tet, Tet′) and panels.

Kinetically controlled narcissistic self-sorting of Pd(ii)-linked self-assemblies from structurally similar tritopic ligands

Abstract: Although many examples of self-sorting have been reported, self-sorting of structurally similar building blocks is potentially difficult. Herein, we present the narcissistic self-sorted state from two kinds of structurally similar...
