摘要

合成了Yb (III)、Nd (III)和Er (III)的异位异构体和配合物，并在近红外区域显示了腐蚀光敏4f发光。异构体配合物的结构允许调整原子核与镧系离子之间的距离。结果表明，不同镧系元素和同分异构体的敏化机理都发生了很大的变化。

4f-LUMINESCENCE OF LANTHANIDE IONS IN REGIOISOMERIC CORROLE COMPLEXES

Isomeric ditopic corroles and complexes of Yb (III), Nd (III) and Er (III) based on them were synthesized and corrole-photosensitized 4f-luminescence in near infrared region was revealed. The structure of isomeric complexes allows adjusting the distance between the corrole core and lanthanide ion. The obtained results show that the sensitization mechanism changes drastically for both different lanthanides and isomeric forms.
