Orthogonal switching of self-sorting processes in a stimuli-responsive library of cucurbituril complexes
S. Schoder, C.A. Schalley – 2017
The self-sorting processes in dynamic libraries of cucurbituril complexes can be switched in an orthogonal way by external stimuli. Protonated phenylpyridine guests form a 2:1 homoternary pi-donor-pi-acceptor complex, while deprotonation makes it a partner for ethylviologen in a 1:1:1 heteroternary complex. Reduction of the viologen instead generates 2:1 homoternary complexes of viologen radical-cation.
