| 摘要: 由缩氨基脲和2-喹啉醛合成了席夫碱配体H2L，并与过渡金属离子Cd2+组装得到了四边形配合物CQ。用X射线衍射对配合物的晶体结构进行了测定，发现其具有I41/a空间群。通过荧光测试发现该配合物在CH3CN溶液中具有较强的荧光，加入间苯二甲酸、对苯二甲酸阴离子后荧光发生淬灭，而加入邻苯二甲酸阴离子荧光无变化，可以将邻苯二甲酸阴离子从其他2种二酸阴离子中区分出来。 |

| Abstract: A novel Cd-based tetranuclear complex CQ ([Cd4H2L4](NO3)2·14H2O, where H2L=bis[2-Quinoline methyl] carbohydrazone) has been synthesized via self-assembly. Single-crystal X-ray diffraction analysis shows that CQ is a molecular square, which crystallizes in an I41/a space group. CQ shows a strong fluorescent emission band in CH3CN solution. The fluorescent titration experiment shows the CQ has a fluorescent quenching effect toward p-phthalate and m-phthalate dicarboxylates, while silent for the o-phthalate one, suggesting it can be used as a fluorescent chemosensor for distinguishing o-phthalate from two other isomers of dicarboxylates. CCDC: 791184. |
