| 摘 要： | 在合成的一类三元离子缔合型铕配合物Eu(tta)4?DEASP中，阳离子基团DEASP做为铕离子的双光子敏化剂，将铕离子的双光子激发波长拓展至生物光学窗口的长波波段1.06 μm。在此基础上合成出一系列DEASP的衍生物，研究阳离子基团的推拉电子能力对于配合物双光子敏化效率的作用机制。通过改变阳离子基团的端基结构可以有效提高双光子敏化效率，有望获得1.06 μm高效双光子吸收诱导荧光的铕荧光探针。

| Abstract: | A new kind of europium-orgainc complex Eu(tta)4?DEASP was synthesized, in which the cation DEASP can play the role of two-photon sensitizer for Eu3+. The two-photon sensitization wavelength of Eu3+ was extended to 1.06 μm. Furthermore, a series ramification of DEASP were synthesized. The analysis on the structure-property relationships demonstrated the following results. Changing the cation only by substituting the terminal donor group, the two-photon sensitization efficiency can be improved evidently. And, this kind of europium complex can be hopefully applied in the field of biological imaging. |
