DOI: 10.1002/ijch.201700096
Abstract: The supramolecular chemistry of host-guest complexes of cucurbit[n]urils (CB[n]) with acidic guests in the ground (HG+) and excited states (HG+*) are reviewed. The effects of CB[n] complexation on the guests’ pKa and/or pKa* values are… read more here.

DOI: 10.1039/c8ce01661e
Abstract: Host–guest complexes between the cucurbit[6]uril macrocycle and phenethylamine ‘natural’ stimulants (ephedrine, synephrine and octopamine) have been obtained in the presence of magnesium ions. Ephedrine and synephrine form partial inclusion complexes with the macrocycle upon insertion… read more here.

DOI: 10.1039/d1dt03925c
Abstract: We describe here a comparative study between two tripodal anion receptors based on selenophene as the binding motif. The receptors use benzene or perfluorobenzene as a spacer. The presence of the electron-withdrawing ring activates the… read more here.

DOI: 10.1039/d2nr03852h
Abstract: The cycloparaphenylene (CPP) nanocarbons are an appealing family of macrocyclic organic semiconductors with size-tunable structures and unique optoelectronic properties, which can be further modulated by complexation with guest molecules. While many π-π-stabilized CPP-fullerene host-guest complexes… read more here.

DOI: 10.1080/00958972.2019.1577962
Abstract: Abstract We have investigated the chirality transfer from 1-phenylethylamine to a 5-amino-1,3-phthalic acid diamide-linked zinc bisporphyrinate through crystallographic and DFT studies. When the hosts were mixed with optically pure 1-phenylethylamine, CD showed moderate signals in… read more here.
