Abstract
The substituent effects on chemical functions of benzo-15-crown-5 derivatives were found to be considerably large and often comparable to the ring-size effects. For example, 4′-aminobenzo-15-crown-5 transported K+ ion 14-times faster than 4′-nitrobenzo-15-crown-5, while 4′-nitrobenzo-18-crown-6 showed 12-times higher transport rate than 4′-nitrobenzo-15-crown-5.
