“…Currently, methods based on the use of supramolecular chemistry are becoming increasingly important in agriculture, not only for the elimination of contaminants but also for the controlled release of certain phytosanitary substances. 11−15 Some of the systems that can be used for the capture of organic molecules are metal organic frameworks, 16,17 calixarenes, 18,19 cucurbiturils, 20,21 bambusurils, 22 cyclodextrins, 11,14 and covalent organic frameworks 23 among others.…”

“…The actual problem in this endeavor is not usually the actual degradation of organic pollutants, as procedures abound for this task, but how to agglutinate the remains of pesticides dispersed through different and extended matrices to perform the elimination.

Rational Design of Efficient Environmental Sensors: Ring-Shaped Nanostructures Can Capture Quat Herbicides

The viability of using [ n ]-cycloparaphenylenes (CPPs) of different sizes to encapsulate diquat (DQ) pesticide molecules has been tested analyzing the origin of the host–guest interactions stabilizing the complex. This analysis provides rational design capabilities to construct ad hoc capturing systems tailored to the desired pollutant. All CPPs considered ( n = 7–12) are capable of forming remarkably stable complexes with DQ, though [9]-CPP is the best candidate, where a fine balance is established between the energy penalty due to the deformation + repulsion of the pesticide molecule inside the cavity (larger in smaller CPPs) and the maximization of the favorable dispersion, electrostatic and induction contributions (which also decrease in larger rings). These encouraging results prompted us to evaluate the potential of using Resonance Raman spectroscopy on nanohoop complexes as a tool for DQ sensing. The shifts observed in the vibrational frequencies of DQ upon complexation allow us to determine whether complexation has been achieved. Additionally, a large enhancement of the signals permits a selective identification of the vibrational modes.

“…Current developments concerning bambus[6]uril are focussed on modification of this macrocycle, including the replacement of the oxygen atoms on the methyl‐substituted urea by heteroatoms and the introduction of other groups on the N atoms bearing the methyl groups, to achieve new supramolecular properties. For example, dodeca(4‐carboxybenzyl)bambus[6]uril 2 , as a derivative of water‐soluble bambus [6] uril, is obtained by introduction of 4‐carboxybenzyl on N atoms bearing the methyl groups and the macrocylic host has a high affinity for anions, and its binding with bipyridinium guests in water was investigated . Riina and co‐workers discovered the cyclohexyl‐substituted hemicucurbiturils, which exhibited interested chiral recognition due to the chiral substitutes, cyclohexyl groups .…”

Supramolecular Interactions of Bambus[6]urils with Quinoline and 6‐Hydroxyisoquinoline Hydrochloride Salts

et al. 2018

The host‐guest interactions of bambus[6]uril and dodeca(4‐carboxybenzyl)bambus[6]uril with quinoline and 6‐hydroxyisoquinoline hydrochloride salts have been investigated by means of 1H NMR, fluorescence emission spectroscopy and molecular simulation. The 1H NMR spectra confirmed the host‐guest interactions through changes in the proton signals of the guests in the presence of the host. The changes of fluorescence emissions of guests upon addition of increasing amounts of bambus[6]uril suggested the formation of host‐guest complexes in a ratio of 1:1. Additionally, calculations with a semi‐empirical PM6‐D3H4 method provided insight into structures of the supramolecular complexes.

A Self‐Assembled Cage Binding Iodide Anions over Other Halide Ions in Water

A triangular‐prism shaped cage was self‐assembled by the formation of a dynamic covalent bond, namely a hydrazone, in acidic aqueous solution. The hexacationic host bears a number of relatively acidic protons pointing inside the cage cavity, which is able to accommodate an iodide anion selectively in water over other halide anions such as F−, Cl−, and Br−, which are more hydrated. As a comparison, a macrocycle analogue bearing fewer positive charges and fewer hydrogen bond donors shows no anion binding ability. As inferred from the single‐crystal structure and theoretical calculations, the ability of the cage to selectively recognize iodide anions results from the combination of electrostatic forces, C−H⋅⋅⋅I− hydrogen bonds, and the hydrophobic effect.
