Notably, compounds 12–14 can be described as a 3D open–framework with nano–channels, compound 15 can be described as a 3D open–framework with double helical channels, while compound 16 can be described as a 3D heterochiral coordination polymer with double helical channels, which can be obtained by spontaneous resolution from the racemic phosphonic acid.X–ray powder diffraction analysis shows that compound 16 is a pure phase. Surface photovoltage spectroscopy of compound 16 indicates that it possesses positive SPV response in the range of 300–600 nm and shows p–type semiconductor characteristic.

值得注意的是，化合物12-14为具有一维纳米孔道结构的三维开放骨架结构，化合物15是具有双螺旋孔道的三维开放骨架结构，而化合物16是外消旋的有机膦酸配体通过自发拆分而形成的具有双螺旋孔道的多手性三维开放骨架结构。X-射线粉末衍射分析表明化合物16为纯相；化合物16的表面光电压光谱分析中，在300-600nm范围内有3个正的光(来源：ABC论文12网www.abclunwen.com)伏响应带，表明它具有p型半导体的特征；化合物16的诱导表面光电压谱进一步确定它的p型半导体的特征；磁性研究表明，化合物16中两Mn原子之间存在弱的反铁磁相互作用。
