请帮我翻译以下内容：棒状次级结构单元ROD-SBU与有机配体所组装而成的ROD-MOF是我们课题组中一直在研究的的特色结构由于ROD-MOF中的金属离子呈现一维链状排布与配体配位形成的框架材料通常也会具有同向的孔道分布。

The rod-shaped secondary building unit (ROD-SBU) assembled with organic ligands to form ROD-MOF is a characteristic structure that our research group has been studying. Due to the one-dimensional chain arrangement of metal ions in ROD-MOF, the framework material formed by coordinating with ligands usually has a directional pore distribution.
