在溶液中

The results indicate that the weak election-withdrawing group 4-hydroxymethyl in 4-position of pyridine in 4-HMDPA could weaken the fluorescence intensity of the lanthanide complexes. The contradistinctive experimental results show that the fluorescence intensities of these complexes are related to pH value of the aqueous solution and the dipole moment of solvent molecule: in the neutral aqueous solution,the fluorescence intensities of these complexes were strongest,while the less the dipole moment was,the stronger the fluorescence intensity was.

结果表明，在吡啶4位引入弱吸电子基团4-羟甲基会减弱稀土配合物的荧光强度；在水溶液中稀土配合物与溶液的pH值有着密切的关联，中性水溶液中荧光强度较大；分子偶极矩较小的溶剂中稀土配合物荧光强度较强。
