Abstract

A new type of homochiral metal-organic nanotubular structures based on metal phosphonates are reported, namely, (R)- or (S)-[M(pemp)(H2O)2][M = Co(II) (1), Ni(II) (2)] [pemp(2-) = (R)- or (S)-(1-phenylethylamino)methylphosphonate]. In these compounds, the tube-walls are purely inorganic, composed of metal ions and O-P-O bridges. The cavity of the nanotube is hydrophilic with one coordination water pointing towards the center, while the outer periphery of the nanotube is hydrophobic, decorated by the phenylethyl groups of pemp(2-). The thermal stabilities, adsorption and proton conductivity properties are investigated.

摘要

报道了一种基于金属膦酸盐的新型同手性金属有机纳米管结构，即(R)-或(S)-[M(pemp)(H₂O)₂] [M = Co(II) (1)，Ni(II) (2)] [pemp(2-) = (R)-或(S)-(1-苯乙氨基)甲基膦酸盐]。在这些化合物中，管壁完全是无机的，由金属离子和O-P-O桥组成。纳米管的内腔是亲水的，有一个配位水指向中心，而纳米管的外周是疏水的，由pemp(2-)的苯乙基修饰。研究了其热稳定性、吸附和质子传导性能。
