Artificial light-harvesting systems based on supramolecular self-assembly multi-component metallogels

Abstract

This paper proposes a strategy for fabricating new artificial light-harvesting systems (ALHSs) based on supramolecular multi-component metallogels. Al3+ was introduced into a solution of an acylhydrazone compound (L) in DMSO...

A supramolecular cascade assembly with a two-step sequential energy transfer process for enhanced photocatalytic performance

“…Due to the non-covalent interaction properties exhibited by supramolecular assemblies, supramolecular LHSs can be readily prepared through the simple mixing of corresponding building blocks in comparison to covalent LHSs. [7][8][9][10][11][12][13][14][15][16][17][18][19] There has been a growing scientic interest in noncovalent assemblies exhibiting high photoinduced energy transfer efficiency; various supramolecular articial LHSs have been developed, including dendrimers, 20,21 organic gels, 22,23 porphyrin arrays, [24][25][26][27] and organic-inorganic hybrid materials. [28][29][30][31] In order to achieve an efficient supramolecular LHS, it is crucial that the donor induces uorescence emission enhancement in the supramolecular assembly rather than uorescence quenching.…”

Construction of an Artificial Light-Harvesting System Based on an Aggregation-Induced Emission Type Multiperformance Supramolecular Fluorescent Gel

“…In particular, the molecule Bh (a bibenzimidazole compound) synthesized by us cannot self-assemble into gels. Inspired by the concept of a chaperone gel proposed by Liu et al, our group used 1,3:2,4-dibenzylidene sorbitol as a carrier to prepare ALHSs in a gel state, but the gels formed by noncovalent interactions between molecules were easily damaged under strong shock. As a result, many practical applications are restricted.…”

A crown ether embedded responsive π-gelator for transition from a one-component gel to a two-component gel

“…[17][18][19] Despite the intelligent utilization of host-guest chemistry involving macrocycles to create responsive gels, instances where a macrocycle can not only serve as a scaffold to form a single-component gel but also transform into a two-component supra-gelator through host-guest recognition remain rare. [20][21][22][23] This rarity might be attributed to the serendipitous discovery of most LMOGs, posing a challenge for macrocycle-embedded gelators to hierarchically assemble into gels at both molecular and supramolecular levels. 24 In this study, we introduced a novel crown ether-appended supramolecular gelator, denoted as 1 (Scheme 1a), demonstrating exceptional gelation properties and responsiveness to various stimuli.…”
