| Abstract: | A new anthracene-based macrocyclic host (H) was designed and synthesized. H has a molecular box-type structure with a flexible cavity. It exhibits highly strong binding affinities towards selected cationic model guests, butyl viologen (BV), dibutylammonium (DBA), and octyltrimethylammonium (OTMA). For example, the association constant of H and BV is up to (2.2?±?0.3)?×?107?M?1; it is interesting to observe host-guest charge-transfer band (and color change) and fluorescence quenching of H’s anthracene unit due to the formation of inclusion complex. |
