Twisted cucurbit[14]uril: A new type of CTE macrocycle for Fe sensing

Construction of an Artificial Light-Harvesting System with Photocatalytic Activity Based on Nor-seco-cucurbit[10]uril in Aqueous Solution

“…Nor - seco -cucurbit­[10]­uril ( ns -Q­[10]) is composed of five glycolurils linked by two CH 2 – bridges. , Due to this property, ns -Q­[10] has a good application prospect in adsorption and separation, fluorescence sensors, supramolecular polymers, , and supramolecular organic frameworks . In recent years, there has been increasing interest in mimicking natural light-harvesting systems based on macrocyclic chemistry due to their potential applications in biological imaging and optoelectronic equipment. − There are two key prerequisites for efficient energy transfer from a donor to an acceptor using the Förster resonance energy transfer (FRET) process. , First, the donor should be densely packed while avoiding intramolecular self-quenching of fluorescence due to the aggregation-caused quenching (ACQ) effect. Second, to ensure that there are several donors for each acceptor, the donor/acceptor ratio should be relatively high.…”

A supramolecular fluorescence array sensor for toxic heavy metal ion detection in environmental water and rice seedling extracts

“…The analyte can specifically react with the fluorescent probe through competition or cooperation to produce optical responses that can be used to detect the analyte. [24][25][26][27][28][29] Therefore, a sensing array can be designed based on the cross-reactivity of the interaction between the fluorescent probe derived from cucurbit[n]uril and the analyte. The use of supramolecular array sensors based on cucurbit[n]uril to detect and recognize multi-target analytes, such as bioactive metabolites, [30][31][32] environmental pollutants, 33 and pesticide residues, 34 has received considerable attention.…”

Highly Efficient Artificial Light-Harvesting Systems Constructed in an Aqueous Solution Based on Twisted Cucurbit[14]Uril

“…It has good water solubility and two unique cavities, which can encapsulate two guest molecules to form a ternary supramolecular complex. Note that it could eliminate the need for any π–π stacking or charge-transfer interaction between the two guest molecules, which is different from other cucurbit­[ n ]­urils, and these properties give it a unique advantage for constructing supramolecular polymers, , which is also a feature and advantage. , Herein, we present two new aqueous ALHS construction via supramolecular self-assembly of water-soluble t Q­[14], a synthetic anthracene derivative (ADPy; Scheme ), and two different fluorescent dyes, namely Nile red (NiR) and rhodamine B (RB). ADPy, a synthesized new AIE molecule, may be regarded as an ideal donor for ALHS in aqueous environments and consists of 9,10-bis­(4-pyridinyl)­anthracene bearing two N -butyl chains with terminal pyridinium moieties that can be specifically recognized by t Q­[14] (the synthesis method is shown in Scheme S1).…”
