Transformation of One-Dimensional Ladders into Two-Dimensional Networks via Simple Solvate Exchange in Single-Crystal-to-Single-Crystal Mode

Abstract

Dimensional transformation of one-dimensional (1D) ladders into 2D networks via simple solvate exchange in the singlecrystal-to-single-crystal (SCSC) mode was observed. Self-assembly of Zn(NO 3 ) 2 •6H 2 O with the new ligand 2,4,6-tris(pyridine-3-yloxy)-1,3,5triazine (L) in acetonitrile gives rise to single crystals consisting of 1D ladders [Zn(NO 3 ) 2 L]•1.5CH 3 CN, and successive solvate exchange of those single crystals in dioxane in the SCSC mode transforms them into 2D networks [Zn(NO 3 ) 2 L]•1.5C 4 H 8 O 2 with a topology of {4 × 10 2 }. The supramolecular transformation between the two species via simple solvate exchange was confirmed by their photoluminescence spectra.

Advances in 2D coordination networks for single‐crystal‐to‐single‐crystal applications beyond confined pores

“…The two skeletal structures are the same except for their helicity; that is, they are a pair of enantiomers. The local geometry of the Ag(I) cation approximates to a typical trigonal arrangement with three N-donors from three chiral Ls, resulting in the construction of 2D frameworks consisting of 72 Transformation of 1D into 2D of {4Á10 2 } via solvate exchange in SCSC mode…”

“…Our recent results indicate that 2D coordination networks are integral to the following task-specific applications such as template for 3D structures of liquid chemicals, template of energy-transfer materials adsorption, solvomorphism materials, separation of xylene isomers, oxidation catalysts, recognition of cyclic compounds, sensing of unstable diiodomethane, recognition of chiral amino acids, and role of solvate in dimension expansion in SCSC mode. [62][63][64][65][66][67][68][69][70][71][72] Whereas researching on the functional behaviors within 2D pores have been published, [73][74][75][76][77][78] the corresponding SCSC specific applications are rare. In this context, we have explored the efficient SCSC applications beyond the molecular open channels.…”

Construction and catalytic effects of solvent- and metal(ii)-dependent products: the process of transformation of 0D structures into 3D structures

“…Discovery of a methodology for synthesis of various coordination architectures via deliberate driving forces is a significant challenge, and not concomitantly, is also an intriguing idea in the area of coordination materials. [11][12][13][14][15][16][17][18] A prerequisite to the development of diverse coordination materials is the comprehension of the substantial driving forces behind the formation of different coordination networks for the same components. Furthermore, the process of interconversion between two different coordination assemblies from the same components is a fascinating research topic relevant to developments in efficient adsorption/desorption, molecular recognition, anion exchange, and catalysis.…”

Pyridine-Triggered Fluorescent Switching in Coordination-Induced Allosteric Crystal Transformation

“…However, complex 2 shows a fluorescence peak centered at 538 nm with a fluorescence decay time of 3.85 ns (Figure S11), but the fluorescence intensity is enhanced by a factor of about 3-fold compared to that of complex 1, indicating that the nonradiative decay process enhanced by the 2D weak hydrogen bonding in 1 (Figure S7 and S8). 36,37 The longer lifetime in 2 suggest there is a strong π•••π interaction in crystal packing (Figure 2). 38 The above differences in emission between 1 and 2 can be further understood from the twisting of ligands in the structures.…”
