Controllable supramolecular assembly and architecture transformation by the combination of orthogonal self-assembly and competitive self-sorting assembly

Abstract

New supramolecular polymers were prepared by the combination of orthogonal self-assembly and competitive self-sorting assembly methods.

Direct Evidence of Heteroleptic Complexation in the Macroscopic Dynamics of Metallo-supramolecular Polymer Networks

“…These two ligands are widely employed to form heteroleptic metal–ligand complexes. ,, In principle, if the possibility of the homoleptic complexation by one of the ligands is suppressed, the consequent gain of energy in the case when the other ligand forms a homoleptic complex while the first ligand stays unassociated, drives the system towards the selective formation of heteroleptic complexes. ,,, However, since we simply utilize non-substituted terpyridine and phenanthroline ligands, the parallel formation of homoleptic complexes beside the desired heteroleptic complex is inevitable. Accordingly, the fraction of each complex depends on the coordination-geometry preference of the utilized metal ion.…”

Multistep sequence-controlled supramolecular polymerization by the combination of multiple self-assembly motifs

“…All starting materials were purchased from commercial sources and used without further purification. Compounds M1, 21 M4, 52 and monomer CD 45 were synthesized using reported methodologies as described ahead. 200-300 mesh silica gel was adopted as column chromatography.…”

Regulable Aggregation-Induced Emission Supramolecular Polymer and Gel Based on Self-sorting Assembly

“…Compound 1 , 3 , 4 , 6 , 7 , and 9 were synthesized based on the literature methods. The synthetic routes and characterizations of some intermediates (compounds 2 , 5 , and 8 ) for the preparation of monomers M4 , AE , and N4 were afforded in the ESI† for details.…”

“…Noncovalent reactions are commonly found in various organisms, where molecular precursors with various functions precisely self-assembled together. Inspired by the self-assembly of functional molecules in organisms, a variety of artificial supramolecular systems with different functions and structures have been constructed through various methods. − Among these supramolecular systems, supramolecular polymers (SPs) have drawn considerable attention as the noncovalent interactions can impart unique architectures and natures, such as degradability and self-healing properties. − Various noncovalent interactions including host–guest interactions have been developed to prepare SPs. − SPs can be prepared through single noncovalent interaction or multiple different noncovalent interactions. In comparison, the supramolecular polymers fabricated by multiple noncovalent interactions not only add the structural versatility, but also enable them to possess some special properties due to the convenience of mounting various functional groups, − such as the aggregation-induced emissive (AIE) functional groups.…”
