Architecture transition of supramolecular polymers through hierarchical self-assembly: from supramolecular polymers to fluorescent materials

Abstract

In this work, three different monomers AB2, C2，and TP4 were synthesized. The AB2+C2 could self-assemble to form supramolecular hyperbranched polymer (SHP1) based on crown ether-based host-guest interaction. Upon adding TP4...

Crown Ether‐Based Supramolecular Polymers: From Synthesis to Self‐Assembly

“…Recently, our group reported the formation of the hyperbranched CSP and its topology transformation from hyperbranched to crosslinked structure. [92] As shown in Figure 33, the AB 2 -type monomer 89 was composed of two B21C7 groups and an alkyl triazole group, the homoditopic monomer 90 consisted of two SAS groups; and the monomer 91 consisted of TPEbridged tetrapillar [5] Reproduced with permission.

A cucurbit[8]uril-stabilized 3D charge transfer supramolecular polymer with a remarkable confinement effect for enhanced photocatalytic proton reduction and thioether oxidation

“…Supramolecular polymers have emerged from the combination of conventional covalently bonded polymers and non-covalent bonding motifs. [1][2][3][4][5][6][7][8][9][10][11] Pioneering works by Lehn and Meijer triggered extensive investigations of hydrogen bonding as a driving force for the generation of supramolecular polymers, [12][13][14][15] which were followed by the applications of other non-covalent forces, including coordination, 16,17 donoracceptor interaction, 18,19 solvophobicity [20][21][22] and ionic pairing electrostatic interaction. [23][24][25][26] Most of the early reports of supramolecular polymers have been realized in organic media of low polarity.…”

Supramolecular oligourethane gels as light-harvesting antennae: achieving multicolour luminescence and white-light emission through FRET

“…Thus, SLGs have been extensively used in diverse areas like optoelectronic devices, [2][3][4] fluorescence labels, [5][6][7] biomedicine, [8][9][10] logic gates, 11 self-healing materials 12 and micropatterning of films on flexible substrates. 13 Various kinds of SLG materials, e.g., nanomaterials, 14 organic-inorganic hybrid perovskite systems, 15 low molecular weight gelators, 16 carbon dots, 17 liquid crystals 18 and supramolecular gelators 19 have been exploited. Compared to other kinds of gelators, supramolecular gelators can be achieved easily by physical interactions like electrostatic forces and hydrogen bonding to achieve gelation, and they can undergo reversible gel-sol-gel transitions under changed external conditions.…”
