摘      要：A new artificial transmembrane channel molecule bearing dihydrogen phosphate groups has been *** terminal dihydrogen phosphate groups enable the channel to be highly negatively charged at both ends of the channel *** artificial channel could incorporate into the lipid bilayer efficiently under low *** channel displays high NH4+/K+selectivity due to the electrostatic interaction and hydrogen bonding between NH4+and the terminal dihydrogen phosphate groups.
