A series of europium and terbium complexes based on a functionalized triazacyclononane carboxylate or phosphinate macrocyclic ligand is described. The influence of the anionic group, that is, carboxylate, methylphosphinate, or phenylphosphinate, on the photophysical properties was studied and rationalized on the basis of DFT calculated structures. The nature, number, and position of electron‐donating
描述了基于官能化的三氮杂环壬烷羧酸盐或次膦酸酯大环配体的一系列of和ter配合物。阴离子基团,即羧酸根,甲基次膦酸根或苯基次膦酸根,对光物理性质的影响进行了研究,并在DFT计算结构的基础上进行了合理化。在同一苯基乙炔基支架内,给电子或吸电子芳基取代基的性质,数量和位置发生系统性变化,以优化相应euro配合物的亮度并研究其双光子吸收特性。最后,在细胞成像应用中检查了complex络合物,并对选定的selected络合物作为潜在的氧传感器进行了研究。
