本发明所用的原料均为市面可得产品。
本发明含钕配位聚合物如无特别说明，均按下述方法制备。
将0.2
mmol4,4'-二甲氧基-[1,1'-联苯基]-3,3'-二羧酸（英文为：4,4'-dimethoxy-[1,1'-biphenyl]-3,3'-dicarboxylic acid，具体结构式如下所示）、0.2 mmol4,4'-二甲基-2,2'-联吡啶和0.1 mmol的硝酸钕溶于5 mL水和10 mL二甲基甲酰胺的混合溶剂当中，在室温下搅拌形成混合液A，用无机碱将混合液A的pH调节为8，然后将上述混合液A在60℃下回流12小时得到混合液B。
然后将所述混合液B置入25
mL水热反应釜中在溶剂热160℃条件下加热反应48小时后以5℃/小时降至室温得到所述的含钕配位聚合物。
然后将上述含钕配位聚合物进行结构表征。
该配位聚合物的X射线衍射数据是在Bruker Smart Apex CCD面探衍射仪上，用MoKα辐射(λ = 0.71073 Å)，以ω扫描方式收集并进行Lp因子校正，吸收校正使用SADABS程序。用直接法解结构，然后用差值傅立叶法求出全部非氢原子坐标，并用理论加氢法得到氢原子位置(C−H 1.083 Å)，用最小二乘法对结构进行修正。计算工作在PC机上用SHELXTL程序包完成。
经测试解析可知，该含钕配位聚合物化学分子式为C56H48O12N4Nd，单斜晶系，C2/c空间群，晶胞参数为a= 21.573(2) Å，b= 19.739 (9) Å，c= 23.753(3) Å，α=γ =90º，β=101.43(3)º，V=10037.25(5) Å 3 ，Z=8。
