Abstract A new artificialtransmembranechannel molecule bearing dihydrogen phosphate groups has been synthesized. The terminal dihydrogen phosphate groups enable the channel to be highly negatively charged at both ends of the channel structures. The artificialchannel could incorporate into the lipid bilayer efficiently under low concentration. The channel displays high NH4+/K+ selectivity due to the
摘要合成了带有磷酸二氢基团的新型人工跨膜通道分子。末端磷酸二氢酯基使通道在通道结构的两端都带高负电荷。人工通道可以在低浓度下有效地掺入脂质双层中。由于NH4 +与末端磷酸二氢根基团之间的静电相互作用和氢键作用,该通道显示出较高的NH4 + / K +选择性。
