Neutral versus polycationic coordination cages: a comparison regarding neutral guest inclusion
Résumé
A neutral self-assembled container synthesized from a concave
p-extended tetrathiafulvalene (exTTF) ligand and the cis-Pd(dctfb)2(cod)
complex (dctfb = 3,5-dichloro-2,4,6-trifluorobenzene; cod =
1,5-cyclooctadiene) is described. This molecular host exhibits a
good binding ability for fused polyaromatic substrates. The corresponding
inclusion properties are compared with those of a previously
described analogous octacationic cage, offering therefore
the opportunity to address the effect of the cavity charge state over
the binding of neutral molecules.
