recommendations! Published in 2017 at "Catalysis Today"

DOI: 10.1016/j.cattod.2016.03.050

Abstract: Abstract The use of tri- and tetraphosphonate cavitand hosts in conjunction with tetrabutylammonium halide catalysts led to improved activity in the coupling of 1,2-epoxyhexane and CO2. Catalytic efficiency of the supramolecular assembly strongly relies on… read more here.

DOI: 10.1021/acs.orglett.3c00463

Abstract: We report a chiral deep cavitand receptor based on calix[5]arene stabilized by a cooperative network of hydrogen bonds and having a highly flexible structure. The cavitand displays enantioselective molecular recognition with a series of chiral… read more here.

DOI: 10.1021/jacs.2c11225

Abstract: Controlling bottom-up syntheses from chiral seeds to construct architectures with specific chiralities is currently challenging. Herein, a twisted chiral cavitand with 5-fold symmetry was constructed by bottom-up synthesis using corannulene as the chiral seed and… read more here.

DOI: 10.1021/jacs.9b06749

Abstract: Disinfection byproducts such as trihalomethanes are commonly found in drinking water. Trihalomethanes are formed upon chlorination of natural organic matter (NOM) found in many drinking water sources. Inspired by molecular CHCl3⊂cavitand host-guest complexes, we designed… read more here.

DOI: 10.1039/c9dt03199e

Abstract: Stimuli-responsive supramolecular assemblies are dynamic systems that can reversibly switch between different states upon external stimuli. In this context, metal coordination offers a reliable strategy for the preparation of stimuli responsive supramolecular architectures. Herein we… read more here.

DOI: 10.3390/molecules23123368

Abstract: Crystallization of tetraphosphonate cavitand Tiiii[H, CH3, CH3] in the presence of positively charged amino acids, namely arginine, lysine, or histidine, afforded host-guest complex structures. The X-ray structure determination revealed that in all three structures, the… read more here.
