“…Inspired by the principles of reticular chemistry, we have synthesized, characterized, and unveiled the functionalities of a novel series of deep cavity cavitands, − namely isoreticular covalent organic pillars. Our methodical approach to reticular synthesis has significantly expanded the structural diversity of iCOPs, culminating in the development of COP-1-Cy , COP-1-1/4N , COP-1-1/5N , COP-2 , and COP-3 .…”

In the realm of nanoscale materials design, achieving precise control over the dimensions of nanotubular architectures poses a substantial challenge. In our ongoing pursuit, we have successfully engineered a novel class of single-molecule nanotubes�isoreticular covalent organic pillars (iCOPs)�by stacking formylated macrocycles through multiple dynamic covalent imine bonds, guided by principles of reticular chemistry. Our strategic selection of rigid diamine linkers has facilitated the synthesis of a diverse array of iCOPs, each retaining a homologous structure yet offering distinct cavity shapes influenced by the linker choice. Notably, three of these iCOP variants feature continuous one-dimensional channels, exhibiting length-dependent host−guest interactions with α,ω-dibromoalkanes, and each presenting a distinct critical guest alkyl chain length threshold for efficient guest encapsulation. This newfound capability not only provides a platform for tailoring nanotubular structures with precision, but also opens new avenues for innovative applications in molecular recognition and the purification of complex mixtures.

“…Finally, the DI-SPME-GC-MS method was applied for the extraction of PAHs from snow samples from Antarctica and the Alps, obtaining ΣPAHs in the 32.2-49.5 ng/L and 10.19-59.13 ng/L ranges, respectively. Other important synthetic macrocycles are the resorcinarene-based receptors obtained by the condensation of resorcinol and aldehydes (Figure 11b) [147,149]. As in the case of CDs and calixarenes, the upper rim of the receptors can be functionalized to obtain deeper cavities, tuned polarities, or different complexation capabilities, whereas the substituents at the lower rim are mostly used to tune the macrocycle solubility or to improve the anchoring on a substrate.…”

Solid-phase microextraction (SPME) has been widely proposed for the extraction, clean-up, and preconcentration of analytes of environmental concern. Enrichment capabilities, preconcentration efficiency, sample throughput, and selectivity in extracting target compounds greatly depend on the materials used as SPME coatings. Supramolecular materials have emerged as promising porous coatings to be used for the extraction of target compounds due to their unique selectivity, three-dimensional framework, flexible design, and possibility to promote the interaction between the analytes and the coating by means of multiple oriented functional groups. The present review will cover the state of the art of the last 5 years related to SPME coatings based on metal organic frameworks (MOFs), covalent organic frameworks (COFs), and supramolecular macrocycles used for environmental applications.

“…12 Bowl-like containers like cavitands possess cavities that have one open end and thus can quickly host one or more guests. 13 In this context, calix[5]arene represents a useful scaffold to produce deep cavitands by modifying its upper rim. 14 Lledó et al have recently reported the formation of intramolecular hydrogen bonding-induced calix[5]arene cavitands for including fullerenes and quaternary ammonium salts in chloroform.…”
