请帮我翻译以下内容：图1-15 a ROD-8由于配体TBAPy芘的方向出现无序表现出结构的无序；b将基于Cd的棒状SBU拆成红色所示的之字形梯型结构；c ROD-8的气体吸附测量。77 K下N2的低温吸附等温线195 K下CO2和CH4的低温吸附等温线98

Figure 1-15. (a) ROD-8 shows structural disorder due to the disordered orientation of the ligand TBAPy-pyrene; (b) the Cd-based rod-shaped SBU is disassembled into a zigzag ladder-like structure shown in red; (c) gas adsorption measurements of ROD-8. Low-temperature adsorption isotherms of N2 at 77 K, and CO2 and CH4 at 195 K [98].
